11. upload a better photo or transcribe it in another question

12. Hund's rule

13.   a. The number of subshells in any given shell is equal to that shell's number. Fourth shell (n=4) contains 4 subshells.

        b. 4s, 4p, 4d, and 4f

        c. 4s=one orbital 0; 4p= 3 orbitals -1 0 1; 4d= 5 orbitals -2 -1 0 1 2; 4f= 7 orbitals -3 -2 -1 0 1 2 3

14. Phosphorus

15. ns1

16. 10, 2 by every orbital (it has 5 orbitals)

17. [Ne] 3s2 3p4 or 1s2 2s2 2p6 3s2 3p4

18. 3d5 this is the last Chargeable orbital of manganese so, the angular momentum (Azimuthal) quantum number is 2, because the last orbital charged is d.

19. np3 tells you the answer: 5A or Pnictogens

20. A total of 7 electrons so the atomic number is 7 = Nitrogen
