it is the atomic number which is the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table.

### Re: Z

When doing molecular orbitals and there are two diagrams, Z < 8 and Z $\geq$ 8, all this is saying is that if your molecule has one or both atoms with an atomic number less than 8 (anything before oxygen), then you use the Z < 8 diagram. If both of your molecules have an atomic number greater than or equal to 8 (oxygen and anything following it on the periodic table), you use the molecular orbital diagram for Z $\geq$ 8.
