The electronic configuration of a particular neutral atom is 1s2 2s2 sp6 3s2 3p2. What is the number of unpaired electrons in this atom?
a. 1
b. 2
c. 3
d. 4
e. 0
The answer is 3. I am not sure why. Does the empty orbital of P count as an unpaired electron?
another question:
the lewis structure for NO3 minus. which looks like this O-N=O and another O single bond attached to it. The total number of ground state resonance structures for this ion is?
Answer is 3. I was wondering is the third resonance structure a hybrid? Thanks.
