Question
Chapter 2, Problem 2.37E
Interpretation Introduction
Interpretation:
The presence of a nodal plane halfway between the two nuclei has to be confirmed.
Concept Introduction:
The nodal plane is the region around the nuclei that has zero electron density; thus the probability that any electron can be found within this nodal plane region is zero.

2. Now we will move on to diatomic molecules. In atoms all p-orbitals are equivalent
with m/= 0, and px py with m/= ±1. In diatomic
molecules these orbitals are in fact separated, with pz associated with o orbitals
along the internuclear axis and px py associated with л orbitals (m/= ±1). In
determining electron configurations we do indeed separate them: N₂ (KK¹ 0₂²).
