It needs to lose, or gain, electrons.
ion
When an element becomes an ion, it can either gain or lose electrons. If it loses electrons, it becomes a positively charged ion (cation). If it gains electrons, it becomes a negatively charged ion (anion). The charge of an ion is determined by the number of electrons it has gained or lost.
It will lose 2 to form Sr2+

It needs to lose, or gain, electrons.
Arsenic becomes an ion by gaining or losing electrons. It can either gain three electrons to form the As3- ion (arsenide ion) or lose three electrons to form the As3+ ion (arsenite ion), depending on the reaction conditions.
A chlorine atom will gain one electron when forming an ion. That will give the ion a charge of 1-.
Sulfur can both gain and lose electrons when forming ions. It can gain two electrons to form a sulfide ion (S2-) or lose two electrons to form a sulfide ion (S2+).
In a nitrogen atom's ground state, it has five atoms. The electron will have to gain three electrons to become stable.
Aluminum will lose 3 electrons to form Al3+ ion.
