Hybrid orbitals are a bonding scheme or model of orbitals, experimentally determined to match what actually happens in bonding. Hybrid orbitals are hybrids, or a mix, or atomic orbitals.
Unhybridized orbitals are the regular atomic orbitals that we have always known. Hybridized orbitals are orbitals that represent a mixture of unhybridized orbitals. These orbitals show what actually happens in bonding and help determine the molecular shape.
hybridized orbitals have energy that is between unhybridized orbitals, it can be seen as a blend of different orbitals. such as the sp3 hybridized orbital, which is a blend of the s orbital and the 3 p orbitals, and has an energy that is between the s and p orbitals. this also results in a different bond angle for the atom that has the hybridized orbitals in the molecular structure.
