Question

An atom has four unpaired electrons. The total spin of this atom will be

Answer 1

Answer:

+2 is the correct answer

Answer 2

The total spin is +2.

• One unpaired electron has a spin +1/2.
• The atom has four unpaired electrons.
• To determine the total spin of the four unpaired electrons we have to multiple four with a spin of a single unpaired electron that is +1/2.
• The total spin will be-
• $4 \times \frac{1}{2} = + 2$
• Thus the total spin of an atom that has four unpaired electrons Is +2.
