Understand that a cation is a positively charged ion, which means it has more protons than electrons.
Recall that the charge of an atom or ion depends on the balance between the number of protons (positive charge) and electrons (negative charge).
Recognize that losing electrons reduces the negative charge, resulting in a net positive charge, thus forming a cation.
Note that losing neutrons or gaining protons changes the nucleus but does not directly create a cation through electron loss or gain.
Conclude that the process leading to the formation of a cation is when the atom loses electrons.
