When atoms or molecules gain or lose electrons, they are best described as becoming ions. Ions are charged particles that are formed through the process of gaining or losing electrons.

Atoms typically do not lose protons because that would change the identity of the element. Instead, atoms can lose or gain electrons to form ions with a different charge. Protons are not generally lost by atoms in chemical reactions.
You lose water through urine, feces and perspiration (sweating). You gain water by eating, drinking and metabolic generation.
If you gain internal validity do you lose external validity
When atoms lose or gain electrons, they form ions. These are charged particles.
