You'll get a detailed solution from a subject matter expert that helps you learn core concepts.Atoms are neutral, which means there is an equal number of protons and electrons. Ions are atoms WITH a charge. The charge can be positive or negative. In other words, the atom gains or loses an electron. The proton never changes (if the proton changes, it is a different element)! See here for Sal's explanation: 2:00.

There are a number of ions that are not individual atoms but are composed of multiple atoms that are covalently bonded together. However, this group of atoms is most stable when it has either lost of gained an electron and thus existed as a charged ion. Table \(\PageIndex{1}\) lists some common ions in terms of how many electrons they lose (making cations) or gain (making anions). There are several things to notice about the ions in Table \(\PageIndex{1}\). First, each element that forms a cation is a metal, except for one (hydrogen), while each element that forms an anion is a nonmetal. 21 mar 2022 ... Hadeon Eon: 4.54 to 4.0 Ga.
