1) n=3 ms=+1/2
2) n=6 l=2
3)n=5 l=3 ml=+3
4) n=7 l=6 ml=+5
Help! Explain and answers please. Thank you.

read my answer here first…

then…
*** 1 ***
possible electrons…
(3,0,0,+1/2)
(3,1,-1,+1/2)
(3,1,0,+1/2)
(3,1,+1,+1/2)
(3,2,-2,+1/2)
(3,2,-1,+1/2)
(3,2,0,+1/2)
(3,2,+1,+1/2)
(3,2,+2,+1/2)
total = 9
or you might just notice that you have 1/2 of the s, p, and d electrons possible. 1/2 x (2+6+10) = 9

*** 2 ***
(6,2,-2, +1/2)
(6,2,-2, -1/2)
(6,2,-1, +1/2)
(6,2,-1, -1/2)
(6,2,0, +1/2)
(6,2,0, -1/2)
(6,2,+1, +1/2)
(6,2,+1, -1/2)
(6,2,+2, +1/2)
(6,2,+2, -1/2)
total = 10
or you might just notice that L=2 are the “d” electrons. there are 10 of them in each row.

*** 3 ***
(5,3,3,+1/2)
(5,3,3,-1/2)
total = 2

*** 4 ***
(7,6,+5, +1/2)
(7,6,+5, -1/2)
again.. 2 electrons.
