Solution
From the electronic configuration given above, we observe that element X has 6 valence electrons in the outermost shell. So the group number of element X in the periodic table is 6+10=16.
The element X has 3 electron shells in its atom. So the period number of X is 3. That is X belongs to 3rd period of the periodic table.
