How do you differentiate the different types of bonds that exist between molecules?

Gina G asked:

Hi all,
My chemistry teacher is very vague in explaining things and I don’t quite understand his method behind saying that covalent bonds are week, I thought they were very strong..
I always thought in terms of strenght it was:
covalentmetallicionichydrogen bondingdipole-dipoledispersion forces or am I way off?

I also have difficulty trying to identify network solids and metallic bonds at times, are there any tricks to remembering them?

I wish my chemistry teacher would be better at explaining this stuff….

Thanks so much for any input!

Minitrue asked:

In terms of bonding, I see sulfur sometimes form 4 single bonds with surrounding atoms, and sometimes form 6 single bonds. How do you know which one to follow when you are given the formula for a molecule?

When does sulfur form 6 single bonds in a molecule?

Thx
Does a lone pair of electrons count as a single bond for sulfur?

Does anyone know if government bonds and treasury bills are good investments?

Saturday, January 23rd, 2010
GENERALE asked:

I am looking to invest in government bonds as an alternative to putting my money in a bank which offers a very limited amount of protection ($250,000 FDIC insurance limit). Which bonds are the best to invest in? Which bonds give the best returns and the most amount of protection? For instance, if I place $5,000,000 in government bonds, will my money be protected until the bond reaches maturity? I also was told that the money will be tax free if it is placed in government bonds, is this true? Any help from anyone would be greatly appreciated.

Thanks.
