Atoms have no random details ? If you look at anything macroscopic there is a lot of random details. Like the leaves on a road, or the cracks in a wall etc. Why don't atoms have any random details? They are perfectly round with "points" (electrons) that circulate them. OK, they are not...

I was thinking , if we take into account oly the internal motion of atoms , all collisions will turn out to be elastic. Wont they be?

All right, so what I don't understand about the big bang theory is that when it describes the creation of atoms, does it mean that the particles were already in existence and the explosin only made the particles come together? or were the particles actually created by the big bang? If the...

Me mate says that that you can make Steal from mixing Carbon atom and Oxygen (Transmution) :eek: Basicly stuffing arround with nuclues. As far as I can remember you can't touch the nuclues as the EM forces are too strong. How wrong is he? We made a bet of $20 :smile:

The question is the title.

this is homework problem I'm having some trouble with... i haven't had chemistry yet so I'm not sure how i could convert atoms into kg, and the textbook i have doesn't do any examples of problems like this one... i don't even know where to begin. Deuterium (A=2, Z=1) is an attractive fuel for...

In a mixture of Ne and He at equilibrium, all of the He atoms move faster than all of the Ne atoms. Why is this false? Shouldn't it be true, since Ne atom is heavier than He atom. Thanks for any help

I wish to know whether gravity has any effect on atoms? And if so to what extent ?

I was thinking if you entangled both the electron and positron in a states that both of their orbitals don't interact. Or just entangle the electron with a helium higher orbital electron. Or you entangled a muon with a helium proton(is that even possible?). Is there any way to keep a...

If one could observe the individual atoms making up a piece of matter and note that during a process of change their motion somehow became more orderly, than one may assume which of the following in regard to the system? a. increase in entropy b. decrease in entropy c. gains in thermal energy...

I'm doing an assignment for grade 8 science in which I have to prove whether or not atoms are fact or fiction. I was just wondering if anyone would be able to give me a few tips to help me out with this. :smile:

Hi, i understand that fission breaks apart radioactive atoms into smaller 'slightly more stable' atoms.. and that this process continues until the atoms break down into stable atoms.. i have been wondering if a radioactive atom/isotope once broken down into a stable atom/isotope would...

Does anybody have any thoughts on why atoms that are warm need to radiate heat in order to stop vibrating or bond back together? The obvious example is the thermos. That is a thermos has the hot liquid contained in a glass container with a mirrored surface towards the inside and then a...

I am to arrange the following atoms or ions in order of increasing radius...then give an explanation for the position of S2- in relation to the atoms or ions that come before or after it. Here is what i have so far...in order of increasing radius. K+ K O S2- Cl Now I am not sure...

I am looking for ways to illustrate the chemical makeup of minerals. I belong to a mineral club and I am scheduled to give a presentation to the children about the polymorph mineral group of Kyanite, Andalusite, and Sillimanite. I would like to have images of the atoms that make up these...

When a photon hits an atom it gets absorbed and an electron moves one or more shells up depending on the energy of the photon. When a bigger, many-electron atom gets hit by a photon, can the electrons in the lower shells get excited? I mean when they move up they have to remove the electrons in...

Since my brain is made of atoms I question as to whether atoms are conscious, at least in the brain but possibly even in inanimate objects, possibly varying levels of self awareness.

I'm trying hard to find a decent explanation for someone that an expanding universe doesn't mean that galaxies get stretched out and made bigger; that the planets won't get further away from the sun; that we don't grow bigger etc. I've googled and searched about but a decent explanation of...

Hey, I've just been studying the Bohr model at school and have had a nagging thought in my head. If we have electrons wizzing around an atom. They will slowly collapse into the nucleus (due to gravity & magnetic forces of attraction) and well I guess something will happen that won't...

help pls! since electrons cr8 a magnetic field due to their spin, shouldn't atoms be magnetic? o0

A plasma consists of both ions and uncharged particles of gases. Is it possible for the uncharged particles to fuse or only atoms whose protons have been stripped off can fuse?

How do we determine the magnitude of the nuclear force acting on the nucleus of an atom?

http://xxx.sf.nchc.gov.tw/pdf/hep-ex/0503034 This paper is a review of anti hydrogen production, and how it could be used to test gravity theories.

Three (3) Questions: 1. Keeping in mind the light emitted by Synchrotrons, then taking the electron as a point charge, and assuming that it orbits the proton in accord with a proper 1s type wave function, does that electron continuously emit (and/or absorb) radiation other than virtual pairs...

Because the charges on the electron and proton have the same absolute value, atoms are electrically neutral. Suppose this were not exactly true, and the absolute charge of the electron were less than the charge of the proton by (1.50e-5)e. now its a 4 part question, i think i can do the...

I've got a question ... if atoms cannot be compacted, beyond a certain minute level, how can they exist inside a black hole, and particularly at the 'singularity' point? Wouldn't the fact that atoms cannot be compacted below a certain level falsify the hypothesis of a singularity at the centre...

Is it known what's between atoms, or between the nuclei of atoms and their electrons? There's a great deal of space (relative to the size of the particles) between the electrons of an atom and it's nuclei, so are there some particles in those spaces, or is it essentially a vacuum? Thanks...

Where do atoms go after they have been destroyed for use of the atom bomb, or anything else that destroys atoms. Does the things that make up an atom disaper or form another atom. thanks, quantumgenius

I have a question ... if atoms cannot be compacted, beyond a certain minute level, how could they exist inside a black hole, and particularly at the 'singularity' point? Does the fact, that atoms cannot be compressed beyond a certain point, suggest falsification of the hypothetical singularity...

I have no idea how to do this...any ideas?

Guess I'll be flippin' burgers for the rest of my life guys... I can't figure out the difference between elements and atoms! I've searched the internet and wrote down their definitions and I e-mailed my prof. Here is how he explained it: > Atoms are the fundamental building blocks of matter...

[SOLVED] Hybrid Atoms I should like to know your opinion about the possibility of the existence of atoms whose nuclii are composed of matter and antimatter components (simultaneously). Which and where experiences had been made about it. Thank you.

What is the mass (in grams) of 6.022 x 10^6 atoms Carbon 12? I am given the equation 1 amu=1.6606 x 10^-24 g, but I'm not sure if I should be using this in my conversion factor or not. Can anyone tell me how to set this up? I have a few ideas but unfortunately I don't have any way to check my...

What is the ratio of the radii of muonic hydrogen to hydrogen? Muonic hydrogen consists of a proton and \mu^{-}. How do you calculate this??

Do the electrons revolving around the nucleus have a current associated with them?

String Theory! ok am I getting this right? when people talk about string theory they say that atoms instead of being made out of orbs particles they are waves coming from a fundamental string.

This is a question regarding time and atoms. My question is this: if one were able to stop the occurence of time, or maybe even reverse time, since the atom in forward time is constantly in motion, would the altering of this forward motion cause the atom to fall apart. Would the covalent bonds...

I am confused. Doing Lewis structures is like balancing an equation, putting it together till all the valence electrons work with each other, as far as I can tell. :-p However, some atoms have A TON of valence electrons, like gold which has 25, um, how would I connect it to other elements...

In trying to understand the oscillating electron in any atomic structure you need to remember that the electron is not just orbiting and controlled by the nucleus but has a spiraling velocity along with the nucleus as the atom accellerates in its path through the heavens (Universe). This...

From what I know, the cooling of He-4 atoms causes them to fall into the ground state, making them Bosons. But there's something which confuses me, from what I read, these atoms actually coalesce into one "super-atom". And in quantum theory, it is entirely possible for many atoms to be in one...

Right, as we know from the uncertainty principle we don't know exactly where an electron is, just where it most probably is. This implies that electrons don't follow circular paths like those of planets round the sun (as in the rutherford model) - they must take a more random path. My...

2 H atoms can form a H2 molecule, releasing energy of 5 eV. However, no chemical reaction occurs when 2 isolated H atmos collide! Explain this curious result using the conservation laws. first of all, i don't know what conservation law to use for this question. 2nd i think i don't have much...

Here's my problem: Show that the speed of an electron in the nth Bohr orbit of hydrogen is (alpha*c)/n, where alpha is the fine structure constant. What would be the speed in a hydrogenlike atom with a nuclear charge of Ze? We didn't talk about the fine structure constant in class, so could...

I'm a high school kid taking chemistry, and I'm confused about how atoms get their listed mass. Take Neon for instance, it's got 10 protons, 10 neutrons, and 10 electroncs, it's normally not an ion or isotopic. So from what my teacher's explained, Neon shold have an Atomic Mass of 10 from the...

Hi, I am working on a project in which I need to know the distance between the particles in an ideal gas system. I have tried searching (google) for it but was unable to come with any actual values, just general terms. Can anyone refer me to where I might find this? Thanks

I have to approximately figure out, to the nearest order of magnitude, how many moles of atoms there are in a 12 kg cat.You are also told that The masses of a hydrogen atom, an oxygen atom, and a carbon atom are 1.0 u, 16 u, and 12 u. . all i know is that 1 u=1.66 x 10^-27 kg. From here I...

Why do atoms move faster in a higher temperature? If an atom was initially not moving at all, and then heat was applied to it, would it start moving? If so, what direction will it move in?

What energy do electrons poses in atoms?

I read recently that photons are largely responsible for why matter doesn't collapse in on itself!? For example, the electrons (negatively charged) and protons (positively charged) inside each of the atoms that make up our bodies should ordinarily attract each other and thereby cause us to...

1. Calculate the rms speeds at 20 degrees celcius of atoms of helium (4u)? 2. The escapte speed from the surface of the Earth is 11.2 km/s. Find at what temp. the following gas (O2) have this value as the rms speed? 3. One mole of an ideal monatomic gas is heated from 0 degrees celcius...
