Important consequences of Important consequences of Quantum MechanicsQuantum Mechanics

The locations of the electrons are describedThe locations of the electrons are described by atomic orbitalsby atomic orbitals

A given orbital can contain only 2 electronsA given orbital can contain only 2 electrons(Pauli exclusion principle)(Pauli exclusion principle)

Atomic orbitals on different atoms will can combine to Atomic orbitals on different atoms will can combine to give molecular orbitals but only if their symmetry matchesgive molecular orbitals but only if their symmetry matches
