Argon has 18 protons. In its neutral state, how many electrons does it have?

In a neutral state, all atoms have an equal number of protons and electrons. Protons have a positive electric charge, and electrons have a negative electric charge, so they cancel each other out. When a reaction causes atom to gain or lose electrons, they become electrically charged and are known as ions.
