Aluminum's, or Al's, atomic number is 13. Therefore, an electrically neutral aluminum atom would have 13 protons and 13 electrons. However, Al3+ has 3 less electrons than neutral aluminum, an thus only has 10 electrons.
Al2+ has 13 protonsAl itself has 13 electrons and 13 protons, 2+ means that Al has ''lost'' 2 electrons(and now have 11 electrons), the number of protons stays the same(13)Added:By the way, it is more common to take Al3+ as example, because Al has 3 valence electrons (in its outer shell) to donate to eg. oxygen: Al2O3 is formed.
Polonium has 84 protons and electrons.
Bohrium have 107 protons and electrons.
8 electrons and 8 protons.
6 electrons, protons, and neutrons.
