Question

Part A Identify which sets of quantum numbers are valid for an electron. Each set is ordered (n,ℓ,mℓ,ms). Check all that apply. 3,1,1,-1/2 1,1,0,1/2 3,3,1,1/2 3,3,-2,-1/2 4,3,3,-1/2 2,1,-1,-1/2 0,2,1,1/2 4,3,4,-1/2 3,2,-1,-1/2 3,2,1,1 3,1,-1,1/2 3,-2,-2,-1/2

Answer #1

basic rules:

n = 1,2,3... cant be negative or 0

l = (n-1) and can be 0

m = +/- l and can be 0 as well

spin = +1/2 or -1/2 only

3,1,1,-1/2 --> valid

**1,1,**0,1/2 --> not valid since l = n

**3,3**,1,1/2 ----> not valid since n = l

**3,3**,-2,-1/2 ----> not valid since n = l

4,3,3,-1/2 --> valid

2,1,-1,-1/2 --> valid

**0**,2,1,1/2 --> not valid, n cant be 0

4,3**,4**,-1/2 --> not valid sicne m > l

3,2,-1,-1/2 --> valid

3,2,1,**1** --> not valid, spinc cnat be 1

3,1,-1,1/2 --> valid

3,-2,-2,-1/2 --> valid

g. 5, 2, 1, -1/2
h. 3, 1, -2, -1/2
2. How many possible combinations are there for the values of l
and ml...

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 (ℓ), the magnetic quantum number (mℓ), and
the spin quantum number (ms) have strict rules which govern the
possible values. Identify allowable combinations of quantum numbers
for an electron. Select all that apply.
n = 4, ℓ= 0, mℓ= 1, ms= 1/2
n = 3, ℓ= –2,...
