Question

Which of the following are possible sets of quantum numbers for an electron in an atom? Click the boxes with the correct answers.

(Select all that apply.)

n = 4, l = 1, m_{l} = -2, m_{s} = +1/2

n = 2, l = 1, m_{l} = -1, m_{s} = +1/2

n = 1, l = 0, m_{l} = 1

n = 1, l = 0, m_{l} = 1, m_{s} = +1/2

n = 3, l = 0, m_{l} = 0, m_{s} = +1/2

Answer #1

Answers are B and E

n = 2, l = 1, ml = -1, ms = +1/2

n = 3, l = 0, ml = 0, ms = +1/2

if n = 4, l has zero to 4-1 values those are 0, 1, 2

m has -l to +l values, ex: for l = 2, m has values from -2 to +2.

For A) n =4 means l has 0,1,2,3 values

l = 1 m has -1, 0, +1 values they shown m = -2 therefore it is not possible

for B) n = 2 means l has -2 t0 +2 values

l = 1 m has -1, 0, +1 values they shown m = -1. it is possible

and m_{s} has either +1/2 or -1/2. therfore it is
possible set

for C) l =0 means m_{l} = 0, they shown m_{l} =
0 therefore it is not possible

for D) also same

For E) possible set

Which of the following are permissable sets of quantum numbers
for an electron in a hydrogen atom? The atom may be in an excited

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.
a) n=4, l=2, ml=3, ms=+1/2
b) n=6, l=6, ml= 1, ms=-1/2
c) n=3, l=1,...
