because then it's balanced
In the simplest sense, an atom can either gain or lose an electron to become more stable. Very electronegative atoms like fluorine and oxygen tend to gain electrons, whereas atoms that are less electronegative like the alkali metals tend to lose electrons. In these cases, an electron is sent to a lower energy state, thus making the atom more stable.
to become stable
Atoms rearrange due to chemical reactions, which occur when atoms form or break chemical bonds. This rearrangement happens to achieve a more stable or energetically favorable state. Atoms can gain, lose, or share electrons to form new chemical compounds and achieve a more stable electron configuration.
Cations form when atoms lose electrons, they gain a positive charge as a result.
Atoms gain lose or share valence electrons in a way that makes the atoms more stable

to become stable
Stable I think.
1. Gain an electron. 2. Lose an electron.
For example metals loss electrons and nonmetals gain electrons.
== == == == The answer is an ionic atom.== ==when it gains an electron, it acquires partial negative charge and it's at.weight increaseswhen it looses electron; it acquires partial positive charge and at.weight decreases
to become stable, it will gain an electron from a metallic atom otherwise it will mutually share electron(s) with another non - metallic atom, or even with itself

Helium is already stable. Hydrogen should gain or lose one electron to be stable.
Some atoms gain or lose electrons to form ions because they like to maintain electro-stability . For example, certain atoms such as oxygen will gain electrons to become more stable so they do not react as bad as when their electron shell is not full .
In a nitrogen atom's ground state, it has five atoms. The electron will have to gain three electrons to become stable.
