A cation carries a positive charge and has more protons than electrons. Neutrons do not have a net electric charge, so the number of neutrons does not matter in the calculation. … 548 views Verified answer. It has five electrons in its outer shell, most of its compounds are trivalent. The protons and electrons cancel each other out because protons produce a positive charge, electrons a negative charge, and they have the same amount.

If neutral, there would have to be 18 protons for the 18 electrons. Add your answer and earn points. Rather like a puzzle box containing exactly the right number of pieces, argon and its five cousins does not have any subatomic shortages that need to be amended by donations from other elements, and it doesn't have any extras floating around to donate in turn. Therefore, argon has no electric charge (as with other elements). Next element of the periodic table. There are 2 electrons on the first energy level, 8 electrons on the second level, and 8 electrons on the third energy level. For example, Argon [Atomic #18] has 8 valence electrons so it is considered to have a full M shell. That means there are 18 electrons in an argon atom. 0 0. The number of protons of an atom cannot change via any chemical reaction, so you add or subtract electrons to get the correct charge. It's mass, 40, minus 18 (electrons) equals 22 (neutrons).
