Atoms that have lost or gained electron(s) are called ions. If they are positively charged (lost an electron(s)), they are called cations. If they are negatively charged (gained an electron(s), they are called anions.
An atom that has gained an electron becomes a negatively charged ion.
Ion
positive
They form an ionic compound.
Generically an "ion", specifically gained an electron an "anion", lost and electron a "cation".

neutron
It gains 1.
Ion
It forms a new atom.
