Old DAT Practice Question
I took a full-length DAT yesterday that my friend had...one put out by the ADA a few years ago. A little stumped by this question. Need some help.

"The electronic configuration of a particular neutral atom is 1s^2 2s^2 2p^6 3s^2 3p^2. What is the number of unpaired electrons in this atom?"
I put B-2, but the answer key has C-3. Do you think this is a misprint or is 3 the correct answer?
