When a non-metal gains electrons, it forms:
Anion
Non-metals have high electron affinity and tend to accept electrons to attain the stable noble-gas (octet) configuration.
When a neutral non-metal atom gains one or more electrons, the number of electrons exceeds the number of protons, giving the species a net negative charge.
A negatively charged ion is called an anion (for example, chlorine gains one electron to form Cl-).
A proton is a sub-atomic particle, not an ion formed by electron gain; "neutral" describes an uncharged atom; a cation is formed by loss of electrons, typically by metals.
Hence, gaining electrons converts a non-metal into an anion.
