nodal plane
Quick Summary
A nodal plane is a region within an orbital where there is zero probability of finding an electron. In molecular orbital theory, molecular orbitals are formed from atomic orbitals. These molecular orbitals can have nodal planes, which are areas of low electron density between atomic nuclei. The number and position of these nodal planes influence the energy of the molecular orbital; more nodal planes generally mean higher energy. For example, in the hydrogen molecule (Hā), the antibonding molecular orbital has a nodal plane between the two nuclei, which raises its energy compared to the bonding orbital.123
