Since a lithium atom has 3 protons and 3 electrons, their charges cancel each other out.

For example, if it lost an electron, it would have 3 protons and 2 electrons, resulting in a +1 charge, creating a lithium ion (Li\u207a). On the other hand, if it gained an electron, it would have 3 protons and 4 electrons, resulting in a -1 charge, forming a lithium ion (Li\u207b).
