Other chemical elements, such as carbon, oxygen, gold, and mercury, are made of atoms with many electrons moving around a nucleus of many protons and neutrons.
Teised keemilised elemendid, nagu süsinik, hapnik, kuld ja elavhõbe, koosnevad aatomitest, mille paljudest prootonitest ja neutronitest koosneva tuuma ümber liigub palju elektrone.
