When we looked at assigning the electrons in nitrogen to sites in the 2s and 2p orbitals, we used the 2s anti-bonding site. Which statement about this site is not true?
A) This anti-bonding electron site has the second lowest energy level of all the sites in the 2s and 2p orbitals.
B) Although this site is not desirable for making a bond between atoms, it is a good site in the sense that the electrons can be close to the nucleus.
C) This site can accommodate a maximum of two electrons (i.e., one electron pair).
D) The energy level for this site is very similar to the energy level for the s 2s orbital site.
