Question

What can you conclude from the figure shown?

(a) The Hund's rule has been violated

(b) The Aufbau principle has been violated

(c) The Pauli's Exclusion principle has been violated

(D) This is a valid orbital diagram

Answer 1

Answer:

A. Hund's rule has been violated

Explanation:

There must be one electron with the same spin in each orbital of the same energy before you can put two in the same orbital. In the photo, the 2s sublevel is completely filled before the 1s sublevel (if anything the 1s should have an up spin and down spin, with the 2s having one up spin).
