3.(25pts) Which of the following sets of (n,l, mi, m.) quantum numbers for the H atom are correct. If a given set is incorrect state why this is so. (5,3,-2,+1/2) (3,2,-1,- 1/2) (4,4,2,+1/2) (-5,-1,0, -1/2) (6,1,-1, 0)

Answer 1

a)

n must be a positive number

n can't be -5

Hence, this is not valid

b)

ms can be -1/2 or 1/2.

It can’t be 0

Hence, this is not valid

c)

This is valid

d)

l must be less than n

Here value of n is 4

But value of l is 4

so, l can't be 4

Hence, this is not valid

e)

This is valid

Answer: c and e are valid
