Can 2 atoms of the same element ever have different atomic numbers? Why or why not?

No, having different atomic numbers would mean different number of protons. If that happened, they wouldnt be the same element.

No. There is only one atomic number for each chemical element.
There can be more than one atomic weight for the same element, but if you have two atoms of the same element, they must have the same atomic number.

If an element has an extra electron - it is a heavy version - technically has the same properties but sure as heck can re-act differently, just read up on nuclear weapons
