What is the designation for an orbital with the following quantum numbers: n = 2 and l = 0

How many unpaired electrons are in the ground state electron configuration for chromium? Your answer should be one number.

Homework Answers

Answer #1

1) n=2 (principle quantum number)

      l = 0 (s orbital)

designation for an orbital = 2 s

2) chromium configuration = 1s2 2s2 2p6 3s2 3p6 3d5 4s1

number of unpaired electrons = 5 from d -orbital + 1 from s orbital

                                                = 6
