Positive ions are called cations and negative ions are anions. When an element loses an electron, it becomes positively charged and therefore it is called cations. If the element on the other side gains and electrons, it becomes negatively charged or anion. Ionic compounds usually have cations and anions in the solution (when they ionize). Examples of ions are as follows:
NaCl (sodium chloride in solution) produces ions which are sodium and chloride ions.
`NaCl -> Na^(+) + Cl^(-)`
`Na^(+) -> Sodium Ion` `Cl^(-) -> Chlo ride Ion`
Other example are:
`Br^(-) -> Bromide Ion`
`CO3^(-2) -> Carbonate Ion`
`SO4^(-2) -> Su l fate Ion`
`Ca^(+2) -> Calcium Ion`
`Al^(+3) -> Aluminum Ion`
`NH4^(+) -> Ammonium Ion`
