Term
Molecular Orbital Theory
Definition

Chapter 1

Definition

Chapter 1

 

Idea that orbitals belong to an entire molecular, not just a single atom

Term
Bonding Molecular Orbital
Definition

Chapter 1

 

Type of molecular orbital characterized by the additive combination of two atomic orbitals to form a single, egg-shaped orbital. Electrons spend most of their time in the region between the two nuclei, lower in energy than the other type of molecular orbital.

Term

Definition

Chapter 1

 

Type of molecular orbital characterized by the subtractive combination of two atomic orbitals to form one single orbital shaped like an elongated dumbbell. Electrons cannot occupy region between the two nuclei, higher in energy than the other type of molecuar orbital.
