Question

Which of the following statements is incorrect? a. The set of quantum numbers n = 4, l = 3, ml = –1, ms = 0 is not permitted because ms = 0. b. The set of quantum numbers n = 3, l = 2, ml = 3, ms = is not permitted because ml exceeds l. c. The set of quantum numbers n = 3, l = 2, ml = 1, ms = is permitted. d. The set of quantum numbers n = 2, l = 2, ml = 1, ms = is not permitted because n = l. e. The set of quantum numbers n = 3, l = 2, ml = 0, ms = is not permitted because ml = 0.

Answer #1

**n = 4, l = 3, ml = –1, ms = 0 is not permitted because
ms = 0. ----------------true**

**b. The set of quantum numbers n = 3, l = 2, ml = 3, ms =
is not permitted because ml exceeds l.correct**

**c. The set of quantum numbers n = 3, l = 2, ml = 1, ms =
is permitted. ------- correct**

**d. The set of quantum numbers n = 2, l = 2, ml = 1, ms =
is not permitted because n = l.----- correct**

**e. The set of quantum numbers n = 3, l = 2, ml = 0, ms =
is not permitted because ml = 0.-------------incorrect**

**because if n=3 ,l=2 means**

**
3d-orbital that means it has ml values
n -2,-1,0,1,2**

and ml...

A possible quantum combination of quantum numbers for the single
valence shell electron of K in the ground state is:
A) n = 4, l = 0, ml = 0, ms = +1/2
B) n = 5, l = 0, ml = 0, ms = +1/2
C) n = 5, l = 1, ml = 0, ms = -1/2
D) n = 5, l = 4, ml = 3, ms = -1/2
E) n = 5, l = 0, 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.
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,...
