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

Figure C should correctly represent the  electronic configuration of Sulphur atom.

Explanation:

Sulphur is an element with atomic number 16.

The electrons in the orbitals are arranged in order to follow the Aufbau's rule.

The electronic configuration of Sulphur should be,

The above configuration states that there should be 2 electrons in 1s orbital, 2 electrons in 2s orbital, 6 electrons in 2p orbital, 2 electrons in 3s orbital and 4 electrons in 3p orbital.

Out of the given diagrams, figure B and figure C has such configuration.

Now, according to Hund's rule, the electrons will first fill all the subshells of the orbital and then they will pair up.

Based on the above information, figure C should correctly represent the  electronic configuration of Sulphur atom.

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 =

S- orbital have only one sub-shell and p orbital have three sub-shell .

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 =

Hence, diagram C is true.
