Naming monatomic ions and ionic compounds (article) | Khan Academy
In the center column, we have a diagram of a single, neutral hydrogen atom. It contains one proton and one electron; thus, its net charge is zero. If hydrogen loses its electron, it forms the cation H + (left column). The H + cation has a net charge of 1+ from the one proton in the nucleus since there are no electrons to cancel out the positive charge.
