Elements of nonmetals are likely to gain electrons
- Atoms of elements which are non metals tend to gain electrons easily, This is due to their strong Electron affinity( which is the energy involved when an atom gains additional electron).

- When these elements gain electrons, thy become negatively charged and are now terms Anions.
