Question

F − (Fluorine) ion is having 10 electrons (9 + 1 = 10). Hence, the species which is isoelectronic with F^{-}F − must also have 10 electrons. It’s some isoelectronic species are i)Na^{+}Na + ion it is also having 10 electrons ( 11 – 1 = 10). ii)Ne ion it is also having 10 electrons. iii)Al^{3+}Al 3+ ion it is also having 10 electrons ( 13 – 3 = 10).
