When was Ernest Rutherford's Gold Foil Experiment? I have found quiet a few sites on him and the experiment, but some sites talk about him and don't mention the experiment, and others say somone else did it... It's all very confusing. So if you can find anything please also send me the link.. for now I'll keep looking. Thanks

As I understand each element listed in the periodic table represents a unique type of atom so why are called "elements"? I know that each atom represents the simplest entity that can exist for each element. Also is it true that some elements can only exist in nautre of two or more atoms? Any help would be appreciated.

Please stick to normal open-air hydrocarbon burns. What would be the difference between the color of the flames between, let's say; a gas spill, or kerosene spill, or heating oil spill? Thanks.

I'm really confused.

The # of MO are obtained by counting the atomic orbitals; for every atomic orbital combined, one MO results.

So here's my question (s):

1) To determine the # of MO, which atomic orbitals do we count? The valence atomic orbitals? The atomic orbitals with only 1 e-?

2) Once we have the # of MO, how do we determine how many electrons are in either a bonding or antibonding orbital?

For instance, how would I determine that there are 3 bonding pairs and 1 antibonding pair in C2?

I'm really confused, any help would be appreciated. Thank you.
