Answer:
A positive ion is formed by the removal of electron(s) from an atom or group of atoms.
A negative ion is formed by the addition of electron(s) to an atom or group of atoms.
Explanation:
A positive ion, also known as cation is formed by the removal of electron(s) from an atom or group of atoms until there are fewer electrons than protons. It positive ion because it contains more proton than electron.
A negative ion, also known as anion is formed when an atom or group of atoms gains electron(s) until there are more electrons than protons. It negative ion because it contains more electron than proton.
The formation of both positive and negative ions is the following:
In the field of chemistry and physics, the concept of ion is used to name an atom or a group of atoms that obtains an electric charge by gaining or losing one or more electrons.
The ions can be made up of two or more atoms (polyatomic) of different nature, or of a single atom (monatomic).
We will speak of a positive ions (cations) when it is an ion that has a positive electric charge, they have lost one or more electrons (that is, the initial neutral atom or molecule gave up electrons).
On the other hand, negative ions (anions) are formed from the gain of electrons in a chemical reaction that gave rise to them (that is, the initial neutral atom or molecule accepted electrons).
Therefore, we can conclude that the formation of both positive and negative ions involves the gain or loss of electrons.
