Atomic orbitals combine most effectively to form molecular orbitals when
A) electrons in the orbitals have no spins.
B) electrons in the orbitals have the same spin.
C) the atoms have an equal number of valence electrons.
D) the atomic orbitals have similar energies.
E) only d-orbitals are used in bonding.

Question

Quizplus · Accepted Answer

Atomic orbitals that have similar energies combine most effectively because the energy levels of the atomic orbitals determine the potential energy of the electrons and their likelihood of interacting to form a stable molecule. If the energy levels are too different, the electrons will not be able to form stable bonds.
