Answer 1

n = Principal Quantum number, n cannot be 0

l = Azimuthal Quantum number = 0 to n-1

ml = Magnetic Quantum number = -l , 0 , +l

ms = Spin Quantum number = -1/2 , +1/2

(3) n = 2, then l = 0 to 2-1 = 1 means l = 0,1

ml = -1,0,+1

ms = 1/2

(5) n = 2

l = 0 to 2-1 = 1 means 0,1

ml = -1,0,+1

ms = -1/2

(9) n = 3

Then l = 0 to 3-1 = 2 means l = 0,1,2

ml = -2,-1,0,1,2

ms = -1/2

(10) n = 4

l = 0 to 4-1 = 3 means 0,1,2,3

ml = -3,-2,-1,0,1,2,3

ms = -1/2

(12) n = 1

l = 0 to 1-1 = 0

ml = 0

ms = -1/2
