Here's what I get.

Explanation:

Question 1

enter image source here

Both electrons in the 3s orbital have the same spin.

This violates the Pauli Exclusion Principle: No two electrons in the same orbital can have the same spin.

Question 2

enter image source here

You have no electrons in the 2s orbital, which is between the 1s and 2p levels.

This violates the Aufbau Principle: When adding electrons to an atom, you put them in the lowest-energy orbitals available.

Question 3

You have two electrons in one 2p orbital, but none in the other 2p orbitals.

This violates Hund's Rule: 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.

Question 4

The electrons in the half-filled 4d orbitals don't all have the same spin.

This violates Hund's Rule: 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.

Question 5

enter image source here

You filled the 4d orbitals before you filled the 4p orbitals, which are lower in energy.

This violates the Aufbau Principle.
