Configuration Definition and 253 Threads

So I am doing my lewis dot diagram work, does it matter where i put the valence electors? for example oxygen has 6 valence electrons, i go with using the N E S W (North, east south, west) I put 2 north, 2 east, 2 south but none of west(6 in total so far) but the book puts them in the...

I'll try to make my description quick so you don't tldr me. So I worked on this project in school on a 6.5inch woofer. I took it from an old computer set (creative) and the amp was dead. I designed and built a new dual supply class ab stage amplifier with a low pass filter. So now I don't...

Homework Statement It's only one question. How to transform this ciruit to only one resistor? Homework Equations The Attempt at a Solution

If we have N unique point masses, is it possible to use only internal forces (i.e. forces between each pair of masses) to reach any configuration of the points (modulo rotations and translations)? I assume this is well known, but don't know where to find a proof. Perhaps by induction from N=2...

Is a three dimensional universe not a requirement for electrons to be configured as we know them? Wouldn't atoms at the least have to exist on a three dimensional brane for the electron clouds to exist as they do?

For a defect in a semiconductor. We plot the energy against some "configuration coordinate", noted in general as "Q". What is this coordinate ? In my understanding it is some position related to the defect in question. Also, is the energy plotted in the diagram the energy of the...

Homework Statement My question is in regards to Cd2+ and its electron configuration. In its neutral state the configuration is [Kr]4d^10 5s^2. What is it in its 2+ state? Homework Equations The Attempt at a Solution The answer is either [Kr] 4d^8 5s^2 or [Kr] 4d^10 5s^0 The...

Benzene forms the electron shell configuration of two rings of electrons, parallel to the molecule, shown here http://upload.wikimedia.org/wikipedia/commons/thumb/9/90/Benzene_Orbitals.svg/750px-Benzene_Orbitals.svg.png so my question is, if an electron beam is run through the center of the...

Can someone PLEASE explain the electron configuration for Chlorine. I know it is 1s^2, 2s^2, 2p^6, 3s^2, 3p^5 and that the noble gas configuration is [Ne]-3s2-3p5 but what I don't understand is why is it Ne and not Ar since Cl gains one electron 3p^6, that is Ar not Ne, Ne is 1s^2...

How do we name cyclohexene with E/Z configuration? This compound is symmetric w.r.t. the double bond.

I am trying to calculate the excionic and biexcitonic energies in quantum dots using Configuration interaction method. I tried to calculate the two electron integrals for configuration interaction method. The integrals are of the form: \int\int dr_1 dr_2 \Psi_1(r_1)...

The ground state electron configuration of Carbon atom is 1s^{2}2s^{2}2p^{2} For the electrons, 1s^{2}2s^{2}, L=0, S=0 So only consider electrons of 2p^{2}, and s_{1}=s_{2}=1/2 ---> S=0,1 l_{1}=l_{2}=1 ---> L=0,1,2 For S=0, L=0; J=0, so we have ^{1}S_{0} For S=0, L=1; J=1, so...

Why is something like Fluorine written as 1s^{2}\;\;2s^{2}\;\;2p_{x}^{2}\;\;2p_{y}^{2}\;\;2p_{z}^{1} and not 1s^{2}\;\;2s^{2}\;\;2p_{x}^{2}\;\;2p_{y}^{1}\;\;2p_{z}^{2}? 2p_{y}^{1} and 2p_{z}^{1} should be of the same energy, right? Or is it only a matter of convenience/convention which one...

would you please tell me,in common emitter transistor configuration what is the use of grounding the emitter? thanks

A quick question... When you have to decide the electron configuration for an atom you find the number of electrons in the shell as 2n^2 and the subshell by 2(2l+1). If I'm not mistaken "the shell" is the total electrons in an atom, right ? So for n = 1 it makes sense that there can be a...

Hi, I'm new to this forum and I thought this would be the best place to ask. What is configuration analysis? Thanks for your help!

how impedence matching is done with any transistor configuration ? hello friends...we all know that common collector transistor have higher input impedence and lower o/p impedence ...and this is very good for impedence matching...but i don't know how impedence matching is done by them... can...

Why do rigs have their front wheel rims sticking out while other rims stick in? http://www.discountramps.com/truck-wheel-risers-1.jpg My first theory was that it allowed them to use a common axle length for all axles on a rig but subsequent observation reveals that that's not the truth...

I have two configurations (set of points, each with its x and y coordinate) that should be compared. In order to do this, I should perform the operation so that both configurations are centered at the origin. I understand that the operations are to be performed on x and y axis, but I'm not...

Im rereading griffiths electrodynamics and noticed all the derivations of energy to assemble a given charge config assume you can bring charges in from infinity and stick them down. In reality if you tried this inevitable some of the particles would accelerate away or towards the incoming...

Hello; My physics teacher told me that there was a way to calculate the ionic charge of a transition metal given its electronic configuration, but he did not tell me how, because it is 'too complicated'. I can't find any useful webpages on the subject, either... my teacher said that the...

What does the field of the London Moment do as it approaches the surface of the spinning SC? A: Continue to the surface undiminished then fade away in a few penetration lengths, exactly as though it were an exterior field being applied to a stationary SC. B: Start fading away a few...

Ok so I've been wondering, how is it that physicist's EXPERIMENTALLY determine the ground state configuration of electrons in a particular atom? In other words do they use emission spectra/thermodynamic calculations/etc? Also, if ground state represents an atom's minimal energy state, which...

Obviously because there is a minus sign in |0 0> = 1/sqrt(2)*((up)(down)-(down)(up)) but I guess I am not completely sure why |0 0> can't equal 1/sqrt(2)*((up)(down)+(down)(up))... m still equals zero, and aren't we pretty much arbitrarily deciding that the spins are oppositely aligned in the...

I keep reading that the configuration space of a given system is the "space of all it's posible positions". Along with this is the inevitable example that the configuration space of a double pendulum is the 2-torus, S^1 x S^1. This makes sense: the possible positions of the first bob is a circle...

Assume you have two parallel plates with charges +q and -q. Now, you fill the space in between with two different dielectrics so that if you were to move straight from one plate to the other, you would be in the same dielectric. (In other words, the two dielectrics do not form "layers.")...

When we are taught relativity we never seem to be asked to consider how the configuration of objects in frames moving relative to ours actually got there. It just seems that we imply that is the way they always were and so an actual congruence measurement of direct comparison in the same frame...
