Lithium Definition and 106 Threads

We have to give the formula for lithium nitride. I know the answer is Li3N. But, I do not understand why it is not Li2N2. I drew the lewis structure and there is a way to arrange that molecule. Why don't we specify with the prefixes the number of atoms trilithium nitride? In a same way, why...

Why can't primary lithium batteries (that are not lithium IONS) be developed as secondary batteries? Can someone explain this to me?

Hi all! I would like to know how to charge a lithium polymber battery of 3.7V, 110mA battery. Anyone has the circuit ? Help! Thank you!

Lithium Hydride contains more hydrogen per unit volume than liquid hydrogen does, so what is stopping us from developing a Lithium Hydride storage solution to supply hydrogen to a vehicle's engine? The reactivity of the substance would throw up some substantial challenges, but compared to...

How to fix my laptop battery Lithium Ion when it doesn't charge.My friend says that his battery became stronger when he put it on the refrigerator,so i did also because my battery is having a problems with its charging.When it became full,and I'm using it before 20% it shutdown itself.But,after...

For my project, the Lithium Ion Polymer Battery - 3.7v 2600mAh powers arduino, transmitter and a few other parts. My whole design works on 3.3v. I'm trying to build a circuit to indicate the status of the battery using LED. When the voltage of the battery is consumed below 3.0v, I want to...

My probelms is thus: I have a numerous samples that my company runs and I am trying to figure out how the lithium borate fusion of samples like silicon dioxide or Fe-Ti stabilize after excitation from xray to fluores. Becasue the way I would think is that the smaple/LiT is stable before...

So I have learned that all batteries have an internal resistance which will limit the current that it can output, so that you can't discharge a huge battery in a split second because of that internal resistance. But what I am wondering is, at what point is it dangerous to draw too much current...

The energy needed to strip all three electrons from a Li(g) atom was found to be 1.96*10^4 kJ/mol. The first ionization energy of Li is 520 kJ/mol. Calculate the second ionization energy of Lithium atoms (the energy required for the process) Li+(g) ---> Li+2 + e- Equation: frequency =...

I'm teaching periodic trends in a Gen. Chem. course, and it's commonly mentioned that the radius of an Li+ ion (90 pm) is smaller than that of the neutral Li atom (~160 pm), with the dominant reason being that the valence 2s1 electron was removed. The same trend shows up for the other alkali...

How to avoid formation of Lithium Chromate ? I am willing to make a glass batch which consists of Li2O and Cr2O3 as well as other stuff... My concern is Lithium Chromate which shouldn't form due its undesirable color. How can I possibly avoid formation of Lithium Chromate at about 1000C ...

I recently saw a science documentary saying that there is a lot of lithium on the sun's surface - since lithium is heavier than H and He wouldn't it sink to the core of the sun? How does it stay on the surface?

Homework Statement A thin target of lithium is bombarded by helium nuclei of energy E0. The lithium nuclei are initially at rest and are essentially unbound for this high-energy collision. A nuclear reaction can occur in which 4He + 7Li → 10B + 1n −2.8 MeV The collision is inelastic, and...

Hi all, I've recently encountered the problem of cleaning paraffin oil off a lithium foil. Unfortunately, I am no chemist, and thus am not too sure what will and will not react with the lithium itself (which is something I need to avoid). I had a look for possible solvents that I could use and...

Hi, I have a sansa Clip that is 2 years old. Still works well. I know that one day the non-replaceable battery will die. If I use it 2-3 hours a day everyday during "dead" times like travel, how many years on average can I expect out of it? In terms of money, Should I sell it and buy a new...

“There are several ways in which a planet can disturb the internal motions of matter in its host star, thereby rearrange the distribution of the various chemical elements and possibly cause the destruction of lithium. It is now up to the theoreticians to figure out which one is the most likely...

I am having an issue calculating the first few energy levels of Lithium. To add, electron-electron repulsions are ignored. Since electron-electron repulsion is being ignored, I am starting with the following, For Hydrogen...

Lithium has been commonly stated as explosive and/or flammable upon exposure to water. What does this mean for its use in electric/hybrid car batteries when there will be traffic crashes in rain that could damage the batteries and thus expose this element to water? Thanks for all informed...

A quick google search reveals conflicting opinions on whether or not this will have a negative impact on battery life. I carry my laptop outdoors with me every day on my walk from the train to the hospital, do I need to worry about the cold ruining my battery?

Not asking for a schematic, more a notion of roughly how challenging this will be.

I got this idea that I could maybe replace the heavy lead acid battery on my motorcycle with a lithium ion polymer battery. I found that you can buy batteries for RC cars that match the power requirements. The lead acid battery is 12 volts, 6Ah. It seams that L.I.P. batteries for RC cars are...

In general (meaning nothing specific), how is it made and how much energy (in joules) input is necessary to make it? I'm not planning on making any or anything like that, but I am curious about the general process and whether or not we can get more energy from using it than what goes into making...

Is there someone here who have a good link for the charging curve of a lithium copper oxyphosphate battery. Thanks.

My kids have a Peg Perego John Deere Gator tractor that uses a 12v battery. https://www.amazon.com/dp/B000G0KT6Y/?tag=pfamazon01-20 The battery requires monthly charging or it will die. The charge is slow and the winter months are a hassle. I could replace the battery but I'd rather...

Hi all, I'm currently in the works of experimenting and writing up my Extended Essay on Chemistry for the IB (it is basically a very long lab report). I have chosen to do the sub-topic of electrochemistry, within which I am interested to do something on the Lithium-ion battery. However, this...

I have a couple of different lithium ion battery packs. On one pack charging current reads 0.1 amps, and on the other 1.5 amps. I already charged the 0.1 amp pack with 0.1 amps, and seems to be working. Now, I'm sort of weary charging the other pack with 1.5 amps. Doesn't that seem too much...

I want to ask you something. What happens with the lithium battery (lets say after 100 times of recharging) and loses its capacity after 2 years recharging? Is it something with the ions or what?
