I don't know about recycling oxygen. But I know they remove exhaled (carbon dioxide)CO2 in the living environments by using (solid lithium hydroxide) LiOH that bonds with CO2 to form (solid lithium carbonate) Li2CO3 and (water) H2O.
Carbon Dioxide is absorbed by Lithium hydroxide canisters that are changed periodically in the space shuttles!
The Space Shuttle External Tank is made primarily from Aluminum/Lithium alloys, AL-2090 and AL-2195.
The sun actually is a giant nuclear fusion reactor, not fission like you see here on earth. The difference is that on earth, we can split atoms to break bonds and release energy. The result is weapons and electricity and nuclear waste. The sun however fuses atoms together to make new ones. An example of this is two hydrogen---->1 helium, 1 helium and one hydrogen----> one Lithium, etc. Energy is again released when the atomic bonds are broken and atoms remade, though no nuclear waste this time.
A solar nebula is made of (roughly) the same chemical composition as a star, namely: 70% Hydrogen 28% Helium 2% random molecules, for example Carbon-12 and Lithium.
Yes
Lithium ions form bonds with fluoride ions to form an ionic compound: lithium fluoride (LiF).
LiF ( Note the use and position of capitals and small case letters.
lithium fluoride
Ionic bond in lithium fluoride.
No. Lithium fluoride contains only lithium and fluorine. An organic compound must contain carbon.
Lithium fluoride is an salt held together by ionic bonds.
An ionic compound, lithium fluoride.
Solid lithium fluoride does not conduct electricity, but either dissolved in water or in molten form lithium fluoride is an excellent conductor.
lithium fluoride, LiF
Lithium Fluoride = LiF
Lithium ions have a charge of +1 and fluoride ions have a charge of -1. The formula unit for lithium fluoride is LiF, which means that the lithium and fluoride ions are present in a 1:1 ratio. So the positive and negative charges cancel each other, and the compound lithium fluoride is neutral.
