You sure are asking a lot of chemistry questions today :) Perhaps, as you have not been receiving many (or any) answers, you may have noticed that this site is not for homework done by proxy. If you look at your chemistry text (or borrow one from a library if you do not own one) and you should be able to find the answers. The internet does not hold the answer to everything, and you will learn a lot more if you find out the information yourself. Good luck with your studies.

Well, "non-reactive or inert" seems to exclude covalent and ion bonds, so what are we left with? Dipole-dipole interactions, van der Waals (induced dipols) bonds, and hydrogen bonds. Van der Waals forces and hydrogen bonds are very important in biology, since lot of water is around. http://en.wikipedia.org/wiki/Hydrogen_bond There is also something with sulfur, but I can't recall it right now.

They don't tend to form bonds at all, because they are nonreactive or inert! One of the exceptions to this rule is Xenon Hexafluoroplatinate. In the heavier noble gases, the electrons are further from the nucleus and can form bonds but I find that there doesn't seem to be a consensus about what sort of bonds they are actually forming. Some sites show Xenon Hexaflouroplatinate with an Xe+ forming an ionic bond and some have an XeF+ ion formed through dimerization.
