Element 13 with 13 protons is Aluminum. To become stable Al will lose its three valance or outmost electrons. leaving the atom with a +3 charge
Aluminum starts with 13 protons and 13 electrons. Its electron configuration is
When Aluminum loses its third level electrons
Another way to solve the problems is by subtraction. Aluminum starts with 13 electrons and loses 3 electrons.
Aluminum as a
