Answer 1

Answer #1

Four type of quantum numbers:

I. Principal quantum number(n): Possible values are 1,2,3,……

II. Angular momentum quantum number (l): possible values are 0,1,2,3,…….,(n-1)

III. Magnetic quantum number (ml): Possible values are –l,…..,-1,0,+1,….,+l

IV. Spin quantum number (ms): Possible values are +1/2 and -1/2

1)

(C) is not allowed l value can not equal to n value

2)

(B) is not allowed as ml value can only be 0 as l value given is 0
