If iron (Fe) gained a proton it would become cobalt (CO).
The two oxygen atoms share two pairs of electrons, so two covalent bonds hold the oxygen molecule together
Hydrogen ion<span>, strictly, the nucleus of a hydrogen atom separated from its accompanying electron. The hydrogen nucleus is made up of a particle carrying a unit positive electric charge, called a </span>proton<span>. The isolated hydrogen </span>ion<span>, represented by the symbol H </span>+<span>, is therefore customarily used to represent a </span>proton<span>.</span>
