if the spin of one electron in an orbital is clockwise what is the spin of the other electron in that orbital

Answer 1

Hi,
Pauli exclusion principle tells you that if two electrons reside in the same orbital they will have opposite spin (1/2 and -1/2), so your answer here would be anti clockwise.
Hope this helps!

Answer 2

1. B. Orbital Shape

2. C. counterclockwise

3. D. Electrons enter orbitals of lowest energy first

4. C. 6

5. C. 2

6. A. Filled energy sublevels
