The atomic number. It's the same as the amount of protons ou electrons in an atom. But since an electron can leave an atom fairly easily, then the amount of protons never changes.

Of course it never changes, every element has a different amount of protons in its nucleus, it's what identifies it, the amount of neutrons and electrons can change, which leads to isotopes (different neutrons) and ions (different electrons)
