Just electron
An atom that has gained an electron becomes a negatively charged ion.
An atom of a different element.
An atom has no charge. An ion is an atom that has either gained or lost an electron giving it a charge. An atom that has gained an electron is called an anion and is negative, while an atom that lost an electron is called a cation and is positive.

An ion
It forms a new atom.
Generically an "ion", specifically gained an electron an "anion", lost and electron a "cation".
Atoms that carry an electrical charge because they gained or lost electrons are called ions. An atom that has lost electrons will be positively charged, and it is called cation. On the other hand, an atom that has gained electrons will be negatively charged, and it is called anion.
ions
neutron
When an electron is gained, the atom becomes a negatively charged ion called an anion. When an electron is lost, the atom becomes a positively charged ion called a cation.
They form an ionic compound.
