The atomic numbers of aluminium Al and chlorine Cl are given as 13 and 17 respectively. In their present state the number of electrons in Al will be 13 and in Cl will be 17.

Number of electrons in Al3+ will be 10 because it has the valency of 3+ which means it has lost 3 electrons to complete the outermost shell.

Similarly the number of electrons in Cl- will be 18 because its valency is 1- which shows that it has taken 1 electron in its valence shell to complete the orbit.
