Question

The electronic configuration of an element is 2,8,6 to which grp and period ofthe modern periodic table does the element belongs state it vAlency and justify your answer

Answer 1

Atomic no. 16

The element is sulphur

Period = 3rd (no. of shells)

Group = 16th (6+10)

Answer 2

Electronic Configuration → 2,8,6

Number of shells = Period Number

Hence,
It belongs to 3rd period.

Number of valence electron decides group number.

Hence, group is 16th.

Valency of group 16th element is 2.

Extra Information:-
We know that 2,8,6 is electronic configuration of Sulphur.

Valency is 2
