Answer:
The sign of the charge on an ion indicates the number of electrons gained or lost by the neutral atom. An ion with +1, +2 or +3 charge, has lost 1, 2 or 3 electrons respectively. An ion with a -1, -2, or -3 charge has gained 1, 2or 3 electrons respectively.
Note: The question did not state the ions in question.
Step-by-step explanation:
Ions are formed when neutral atoms gain or lose electrons. There are two types of ions; cations and anions.
Cations are positively-charged ions which are formed when neutral atoms lose electrons. Cations are formed by metallic elements as they have a greater tendency to give up their electrons in order to form ions, i.e. they are electropositive elements. Examples of cations include Na+, Ca²+, Al³+, Fe³+, etc.
Anions are negatively-charged ions which are formed when neutral atoms gain electrons. Anions are formed by non-metallic elements as they have a greater tendency to accept electrons in order to form ions, i.e. they are electronegative elements. Examples of anions include; Cl-, O²-, N³-, etc.
