Re: Reaction Quotient Less than or Greater than 1 [ENDORSED]

What exactly would be the difference between Q and K? Is K just a specific value for Q?

Re: Cobalt and Cobaltate?

When naming a compound with an -ate ("cobaltate"), is there any way we need to specify what the negative charge on the ion is? Or is that simply derived from the other charges?

Exothermic and Endothermic Reactions

What is the difference between an exothermic and endothermic reaction in physical terms? In which one of these is the net change in energy positive and in which one is it negative?

Re: Unpaired Electrons in Molecular Orbitals

When writing out the electron configuration in words, are we supposed to include the 1s and *1s orbitals? I have seen it done both ways and don't really know which way is correct or which one we should be using.

Re: Sulfur and its expanded octet property

I have never seen a molecule in which sulfur is bonded to more than six other atoms, but does it every occur?

Re: Sigma bonds and Pi Bonds

How do you determine, when there is a double bond, which of the two bonds is sigma and which one is pi? Is it completely arbitrary or is there methodology to it?

Re: Ionization energy vs electronegativity vs electron affin

I do understand why electronegativity increases as you move from left to right across a period, but I don't understand why it increases up a group. Could you please explain this?
