My sense is that the electrons determine how the atom behaves to the outside world (i.e. how it behaves chemically), so why is it the number of protons that determines the element? If I have an ion, how different is it such that it is the same element? Or if I have two atoms with the same electron shell, one with X protons and the other with x+1 protons, do they behave the same even though they are called different elements?
