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.
Electrons have a negative charge, so they are usually written as "e-". When an atom loses an electron, the net charge on the atom increases.Suppose a hydrogen atom is hanging out (note that hydrogen is diatomic, but ignore that part for now) and somehow loses its electron.

Ion.
An atom with an overall positive charge is called a cation. Cations are formed when an atom loses electrons, leaving it with fewer electrons than protons, resulting in a net positive charge.
When and atom loses or gains enery, it becomes positivly or nevetivly charged and can become an ion.

The net charge of an atom is always zero, because if an atom gains or loses electrons, causing it to acquire a net charge, we then call it an ion, rather than an atom.
When the number of electrons and protons are not the same in an atom, it becomes an ion. An atom becomes positively charged if it loses electrons (more protons than electrons), and negatively charged if it gains electrons (more electrons than protons).
All atoms are electrically neutral. If an atom gains or loses an electron, we call it an "ion" rather than an atom.

You call it an ion of that isotope. Let's use carbon-14 for example. If a carbon-14 atom gains/loses an electron, you simply call it a "carbon-14 ion".
No An atom may have less, the same, or more neutrons than protons. The number of neutrons determine which isotope of an element you have. You do expect the number of protons and electrons to be the same however. If an atom loses or gains an electron to cause the number of electrons and protons to be mismatched we call that an ion rather than an atom.

It is not always easy to tell whether an atom will lose or gain an electron in a reaction. However, this is a general rule that applies in many cases. Simply put, the atom with the higher electronegativity will gain an electron and the atom will a lower electronegativity will lose an electron.
