Detailed explanation-1: -So any change in the charge of an atom is due to changes in its electron count. If a neutral atom gains electrons, then it will become negatively charged. If a neutral atom loses electrons, then it become positively charged.
Detailed explanation-2: -Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations. Most metals become cations when they make ionic compounds.
Detailed explanation-3: -Or, if an oxygen atom looses an electron then it becomes a positively charged ion because it has more positive protons than it does negative electrons. Molecules are groups of atoms bonded together to create a new type of matter (that is, a compound).
Detailed explanation-4: -Oxygen gains electrons because it wants to be complete or be like the “Noble Gases".
