Lithium occupies the third spot on the periodic table, which, among other things, means it has but three electrons. Two of those electrons are locked up in an orbital zone called the inner atomic shell, a fancy way of saying they are happy in their home and aren’t going anywhere. That leaves one electron with the ability to scoot about within lithium metal, jumping from atom to atom as the mood strikes. Scooting electrons about is a slightly nontechnical way of saying “electricity.”
