number, or combination of quantum numbers, is needed to specify a (d) 16 given subshell in an
atom? (a) n (c) n and
Solution
Answers
1) b) 4p
2) d) 16
3) c) n and l
Explanation
There are four quantum numbers
1.Principle quantum number(n)
2.Azimuthal quantum number(l)
3.Magnetic quantum number(m)
4.Spin quantum number(s)
n =1, 2,3,....
l = 0,1,2,..... (s,p, d, f, etc)
for l=l, m ranges from - l to l
s +1/2 and - 1/2
