In has three electrons in its outer shell (notice it is in group 13 and the 3 tells you that) so it will tend to lose those three electrons to form an ion, In+3.
Generally, but not always, atoms with three or fewer electrons in the outer shell tend to lose them. Atoms with 5 or more electrons in their outer shell tend to gain electrons (to make 8). Atoms with 4 tend to form covalent bonds.
would you expect the following atom to gain or lose electrons when forming ions?
what ion is the most likey?
The atom is In how would i do this?
