Question

The diagram shows the electron configuration of an atom of an element for the electrons in the s and p orbitals.

Answer 1

Answer:

C 16

Explanation:

Since there are 6 valence electrons, this belongs in the same column as Oxygen.  In fact, this is a diagram of a neutral oxygen atom with 8 total electrons.

Answer 2

Answer: 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:  $1s^22s^22p^4$

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.
