Atomic number of the element = 16

Electronic configuration = 2, 8, 6

The period number is equal to the number of shells which starts filling up in it.

The atom of an element has three shells. So, the period number is 3.

The atom of an element has six valence electrons in the outermost shell. So, the group number of the element will be 16 (6 + 10).

The valency of an element is determined by the number of valence electrons present in the outermost shell. The atom of an element has six valence electrons in the outermost shell, so the valency of the element is 2.
