The resulting electron structure when the two atomic orbitals combine
A lower-energy, more stable orbital that results from the overlap of wave functions with the same sign.
A higher-energy, less stable orbital that results from the overlap of wave functions with opposite signs.
The molecular orbital formed by head to head or tail to tail overlap atomic orbitals all signal bonds are sigma bonds
Sigma bonds, accommodating two electrons
The bonding molecular orbital formed when two parallel p-orbitals share electrons; exists as electron clouds above and below the sigma bond between the two nuclei
one sigma bond and one pi bond
a sigma bond and two pi bonds
