Explanation:
Detailed explanation-1: -Metal atoms lose electrons from their outer shell when they form ions: the ions formed are positive, because they have more protons than electrons. the ions formed have full outer shells. for elements in groups 1, 2 and 3, the number of electrons lost is the same as the group number.
Detailed explanation-2: -Whenever there is a gain of electrons the element will acquire a negative charge also known as an anion while when an atom loses an electron, the element acquires a positive charge which is also known as a cation.
