Molecular orbitals are formed when 2 atomic orbitals combine. No of AO = No of MO i.e. 2 atomic orbitals = 2 molecular orbitals. 1 of 9 Is the bonding molecular orbital higher or lower in energy? Lower 2 of 9 Is the anti-bonding molecular orbital higher or lower in energy? Higher 3 of 9 Where are the 2 electrons found in a hydrogen molecule? The molecular orbital with lower energy (bodning molecular orbital) than the 2 atomic orbitals that made it therefore it is a more stable place to be 4 of 9 What is the bonding orbital symbol? sigma (sideways 9) 5 of 9 In a hydrogen moelcule, where is the anti bonding molecule? The higher energy orbital (not full) 6 of 9 What is the anti bonding orbital symbol sigma* (sideways9*) 7 of 9 When does a sigma bond occur? When atomic orbtials combine 'end on' 8 of 9 When does a pi bond occur? When 2 p orbitals overlap side on 9 of 9
