Question

Each of the following sets of quantum numbers is supposed to
specify an orbital. Choose the one set of quantum numbers that's
does NOT contain an error

A. n = 2, l = 2, m = -1

B. n = 4, l = 4, m = 2

C. n = 2, l = 2, m = 0

D. n= 4, l = 2, m = -2

E. n = 3, l = 2, m = 3

Answer #1

A. n = 2, l = 2, m = -1
n= l = 2
**error** for for n value l
should have 0 to n-1 only

B. n = 4, l = 4, m = 2 n = l = 4
**error**

C. n = 2, l = 2, m = 0 n =
l = 2, **error**

D. **n= 4, l = 2, m = -2 no
error correct answer**

E. n = 3, l = 2, m = 3 error for l=2 m= -2 to +2 but m=3 error

5. These sets of quantum numbers are each supposed to specify an
orbital. One set, however, is erroneous. Which one and why?
a. n = 3; l = 0; ml = 0
b. n = 2; l = 1; ml = –1
c. n = 1; l = 0; ml = 0
d. n = 4; l = 1; ml = –2

What are the possible values of n and ml for an electron in a 3d
orbital?
A) n = 1, 2, or 3 and ml = 2
B) n = 1, 2, or 3 and ml = -2, -1, 0, +1, or +2
C) n = 3 and ml = 2
D) n = 4 and ml = -2, -1, 0, +1, +2

Which of the following statements about quantum numbers are
true? (Choose "True" or "False" for each statement.)
True/False Quantum numbers describe the number of
protons and neutrons in an atom.
True/False The ms quantum number has
just 2 allowed values.
True/False The labels on atomic orbitals (1s, 2p, etc.)
are based on quantum numbers.
True/False n, l,
ml, and ms are quantum
numbers.
True/False It takes three quantum numbers to specify an
atomic orbital.

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...

value. (The answer for part (a) has been done for you below.) a. n
= 3, l = 1 b. n = 3, l = 2 c. n = 4, l = 2 d. n = 3, l = 2, ml = –2
e....

configuration for chromium? Your answer should be one number.

19. Which of the following sets of quantum number is not
allowed? A. n = 4, ℓ = 2, mℓ = -2 B. n = 5, ℓ = 0, mℓ = 0 C. n = 6,
