The overlap of electron waves represented by the atomic orbitals may result in constructive (in-phase) or destructive (out-of-phase) interference. c. In-phase overlap between two 1s orbitals results in a new orbital having higher energy than either of the s orbitals. This new orbital concentrates the electron probability between the two nuclei. d.
