Want this question answered?
When an atom loses or gains electrons, it becomes an ion.
covalent/ionic bonding.
When an atom gains electrons, negatively charged anions are formed. When an atom loses electrons, positively charged cations are formed.
Isotope
electrons. Ions exist when an atom gains or loses electrons
An atom that gains or loses electrons is called an ion. If it gains electrons, it results in a negative ion called an anion. If it loses electrons, it results in a positive ion called a cation.

It is called an ion.
A neutral atom that subsequently gains or loses one [or more] electrons is called an ion. If it gains an electron [or electrons] it will have a negative charge. If it loses an electron [or electrons] it will have a positive charge.
Ion
I suppose that you think to ions.
ion
It either gains, loses, or shares electrons.
When an atom gains electrons, negatively charged anions are formed. When an atom loses electrons, positively charged cations are formed.
An atom that has lost or gained an electron or electrons is called an ion. When an atom loses an electron, it forms a positive ion because the protons then outnumber the electrons. When an atom gains an electron, it forms a negative ion because the electrons now outnumber the protons. A positive ion is called a cation (pronounced "cat-ion" not "ca-shun.") A negative ion is called an anion (pronounced "an-ion" not "an-yun.")
