I think its B cause...
When an atom loses an electron, it becomes a cation (positive ion). When an atom gains an electron, it becomes an anion. Ions are created when an atom loses or gains an electron. Atoms can never lose or gain protons, as this would change the fundamental identity of the atom.
if I'm wrong...please don't attack me
The cations are formed when an atom loses electrons. ┬а
тАв The positive ions produced by the loss of one or more electrons are known as the cations. ┬а
тАв The most commonly formed cations take place in the case of the elements, which involve the loss of all the valence electrons. ┬а
тАв The resulting cation exhibits the electronic configuration of the noble gas atom. ┬а
тАв The negative ions produced from the gain of one or more electrons are known as the anions. ┬а
Thus, the correct answer is option b, that is, the cations form when an atom loses electrons.
