Question

Which of the following diagrams correctly shows the electrons configuration of sulfur , with atomic number 16?

Answer 1

The answer is c because its the most likely answe

Answer 2

Answer:

Diagram C

Explanation:

We are given  that Sulfur with atomic number 16.

We have to find that which diagram shows the electronic configuration of sulfur.

S=16

Atomic configuration =$1s^2 2s^2 2p^6 3s^2 3p^4$

S- orbital have only one sub-shell and p orbital have three sub-shell $p_x,p_y\;and p_z$.

Hund's rule:It states that every orbital in sub level  is singly occupied before  any orbital doubly occupied.

Using hund's rule

Atomic configuration =$1s^2 2s^2 2p^2_x 2p^2_y2p^2_z 3s^2 3p^2_x 3p^1_y3p^1_z$

Hence, diagram C is true.
