Question

Which of the following are permissable sets of quantum numbers for an electron in a hydrogen atom? The atom may be in an excited state (ie. the electron need not be in its ground state). Choose all of the correct possibilities.

n = 5, l = 1, ml = -1, ms = -1/2

n = 4, l = 0, ml = 0, ms = -1/2

n = 5, l = -4, ml = -3, ms = -1/2

n = 5, l = 3, ml = -4, ms = -1/2

n = 4, l = 4, ml = 0, ms = -1/2

n = 4, l = 3, ml = +2, ms = +1/2

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

n = 4, l = 2, ml = -1, ms = -1/2

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

n = 6, l = 5, ml = +3, ms = -1

Answer #1

we know that

for a given value of **n** (principal quantum
number) there exist 0 to n-1 values of **l** (azimutal
quantum number) and

for a given value of **l** there exist 2l+1 values
of **m** (magnetic quantum number) which are from -l
to +l including 0.

basing on the above rules the possible orientations are

n = 5, l = 1, ml = -1, ms = -1/2

n = 4, l = 0, ml = 0, ms = -1/2

n = 4, l = 3, ml = +2, ms = +1/2

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

n = 4, l = 2, ml = -1, ms = -1/2

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

Which of the following are permissable sets of quantum numbers

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,...

Determine whether or not each set of quantum numbers shown could
correctly describe an electron in an atom. (Choose "Possible" or

n = 3; l = 3; ml = -2; ms = 1/2
n = 3; l = 2; ml = -2; ms = 3/2
n = 3; l = 1; ml = 2; ms = 1/2
n = 3; l = 1; ml...

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

Point out every mistake with the following set of quantum
numbers for an electron in a hydrogen atom, and then write a new,
valid set of quantum numbers with the magnetic value, and find the
energy of that electron for the new quantum numbers you picked
