Question

Label the following quantum number sets as correct or incorrect.

i) n = 2, l = 1, ml = 0, ms = -1/2

ii) n = 5, l = 0, ml = -2, ms = +1/2

iii) n = 4, l = 2, ml = +2, ms = -1/2

Answer #1

for some n

value of l can be from 0 to (n-1)

and for each l

value of ml can be from -l to l

ms = -1/2 or +1/2

i) n = 2, l = 1, ml = 0, ms = -1/2

it satisfy all the above given condition

so, this set of quantum number is correct

ii) n = 5, l = 0, ml = -2, ms = +1/2

for l = 0

ml can have only one value that is o

so, ml = -2 is incorrect

so, this set quantum number is incorect

iii) n = 4, l = 2, ml = +2, ms = -1/2

it satisfy all the above given condition

so, this set of quantum number is correct

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...

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

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,...

No explanation, just answers

5. These sets of quantum numbers are each supposed to specify an
orbital. One set, however, is erroneous. Which one and why?

c. n = 1; l = 0; ml = 0
d. n = 4; l = 1; ml = –2
