lowest shell “s”

Question 4

can electrons fill one orbital with the same spin?

Answer 4

no

Question 5

what is Hund’s rule?

Answer 5

electrons fill each orbital singly before any orbital gets a second electron

Question 6

what are the three general principals?

Answer 6

1. Electrons enter orbitals of lowest energy first.
2. An atomic orbital can contain 2 electrons at the most.
3. When electrons occupy orbitals of equal energy, an electron occupies each orbital until there is one electron in each orbital.
