Question

Give the set of four quantum numbers that represent the last electron added (using the Aufbau principle) to the Ni atom. Give the set of four quantum numbers that represent the last electron added (using the Aufbau principle) to the Ni atom.

a) n = 4, l = 6, ml = 0, ms = -12
b) n = 3, l = 2, ml = 0, ms = -12
c) n = 3, l = 1, ml = 1, ms = -12
d) n = 4, l = 3, ml = 3, ms = +12
e) n = 3, l = 2, ml = 2, ms = +12

Answer 1

B

Step-by-step explanation:

That electron is found in the 3d orbital.

ml=-2,-1,0,1,2

n=3

l=2

ml=0

ms=-1/2

Since it must be of opposite spin according to Pauli exclusion principle.
