When an atom loses an electron, it becomes a positively-charged ion. This is because it now has more protons than electrons, giving it a net positive charge.
Now, let's consider what happens when the positively-charged ion approaches another positively-charged ion. Since both ions have a positive charge, they will repel each other. This repulsion occurs because like charges repel each other according to the fundamental principle of electrostatics.
So, in this case, option A is the correct answer: The ions will repel each other.
