A sodium atom has 11 protons and 11 electrons. It has a neutral charge. The Na + ion is formed from the loss of one electron. Because it has lost an electron, it has more protons than electrons; the overall charge of the sodium cation is positive. We've always found it useful to think of the "t" in cation as ...

The properties of an element are determined by its outermost electrons, or those in the highest energy orbital.
WebIt has 4 valence electrons, so it can make a 4+ or a 4- charge. But because of its relatively stable half filled orbital, most of the time it takes part in covalent bonding like in organic molecules. On occasion, Carbon can ionize, most commonly 4+.
