The diagram shows the electron configuration of an atom of an element for the electrons in the s and p orbitals.
diagram is attached to question.
what is the group number of the element in the periodic table?
a). 1
b). 2
c). 16
d). 17

The correct answer is Option C.

Explanation:

We are given an image having electrons around the nucleus of an atom.

Total number of electrons around the nucleus = 2 + 6 = 8

The electronic configuration of the element having 8 electrons is:  

As, the last electron is entering p-subshell, the element belongs to p-block of the periodic table.

The rule for determining the group number for p-block element is:

Group number = Number of valence electrons + 10

The number of valence electrons = 2 + 4 = 6

Group number = 6 + 10 = 16

Hence, the correct answer is Option C.
