Question

Quantum numbers arise naturally from the mathematics used to describe the possible states of an electron in an atom. The four quantum numbers, the principal quantum number (n), the angular momentum quantum number (?), the magnetic quantun number (m), and the spin quantum number (ms) have strict rules which govern the possible values. dentify allowable combinations of quanturn numbers for an electron Select all that apply. n = 5,2= 2, m,--2, m+1/2 n=3,1=-1, m1,m=-1/2 n= 4,1=0, m n=3,Fs1.rn«-1.MF-1/2 1, m+1/2

Explanation / Answer

for option 1:

This is valid

for option 2:

l must be less than n

Here value of n is 2

But value of l is 2

so, l can't be 2

Hence, this is not valid

for option 3:

l can't be negative

l can't be -1

Hence, this is not valid

for option 4:

Value of l is 0

So, valid values of ml are [0]

so, ml can't be 1

Hence, this is not valid

for option 5:

This is valid

for option 6:

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

It can’t be -1

Hence, this is not valid

Answer: option 1 and 5
