Hey mate your answer is here

Explanation:

The labels s, p, d and f blocks of the Periodic Table refer to the subshell that is being filled with electrons.

Group 1 elements occur at the beginning of a new row (Period) of the Periodic Table.

The highest energy level (valence shell) contains only 1 electron in an s subshell.

Group 2 elements occur directly to the right of Group 1 elements.

The highest energy level (valence shell) contains 2 electrons, both electrons occupy an s subshell.

The s subshell for this energy level (shell) is now full.

The highest energy level (valence shell) of a Group 13 element already has 2 electrons in an s subshell, so the next electron occupies a p subshell to make 3 valence electrons in total (2 s electrons + 1 p electron).

As you proceed from left to right across the Period from Group 13 to Group 18 elements, electrons are being added to the p subshell.

Group 18 elements have 2 s electrons and 6 p electrons in their highest energy level (shell) which completes the s and p subshell.

Transition metals are filling their d subshell with electrons, starting with Group 3 elements which have 1 electron in a d subshell.

Group 12 elements have 10 electrons in a d subshell, which corresponds to a completed d subshell.

Lanthanoids and actinoids are filling their f subshells with electrons.

Can you apply this?
