"The element has 82 protons and 82 electrons for a net neutral charge. There are 5 electron shells that are completely filled and 4 electrons in the 6th shell. The outer 4 electrons are available for chemical reactions. (Refer to the shell model which shows a dot for each electron). These outer electrons are named 6s2 and 6p2 and they can escape from the atom through a chemical reaction called oxidation to create a lead ion that has a +2 charge (missing 2 electrons) or a +4 charge (missing 4 electrons). The molecule that receives the electrons from Pb will be reduced. Oxidation and reduction reactions always occur together."
I'll need to do a lot of readings later.
