Electrons are both gained and lost. Electrons are both gained and lost.
Atoms that carry an electrical charge because they gained or lost electrons are called ions. An atom that has lost electrons will be positively charged, and it is called cation. On the other hand, an atom that has gained electrons will be negatively charged, and it is called anion.
Usually three will be lost.
They are gained.
An atom that has gained an electron becomes a negatively charged ion.
Electrons are both gained and lost. Electrons are both gained and lost.
Electrons are the ones gained or lost in a chemical reaction. Electrons are gained in oxidation and lost through the chemical reaction known as reduction.

An ion
An ion can have a positive charge (cation) if it has lost electrons, or a negative charge (anion) if it has gained electrons. The charge of an ion is determined by the number of electrons it has gained or lost during the process of ionization.
An atom that has gained or lost electrons is called an ion. If it gains electrons, it becomes a negatively charged ion (an anion), while if it loses electrons, it becomes positively charged (a cation).
Valence electrons can be both lost and gained during a chemical reaction, depending on the types of elements involved. For example, in ionic bonding, valence electrons are typically lost or gained to achieve a full outer shell. In covalent bonding, valence electrons are shared between atoms to complete their outer shells.
Shared
In a redox reaction the number of electrons lost by one particle is equal to the number of electrons gained by another particle.
