which statements regarding molecular orbital theory are true? group of answer choices the orbitals are weighted linear sums of the valence atomic orbitals of a particular atom, and the orbitals remain localized on that atom. when assigning the electrons of a molecule to molecular orbitals, we fill the highest energy molecular orbitals first with a maximum of two spin-paired electrons per orbital. bonding orbitals have increased electron density in the internuclear region, and this accounts for their lower energy as compared to antibonding orbitals. when atomic orbitals are combined in phase (constructively), the resulting molecular orbital is higher in energy than either atomic orbital. the orbitals are weighted linear sums of the valence atomic orbitals of all the atoms in a molecule, and the orbitals are delocalized over the entire molecule. when atomic orbitals are combined out of phase (destructively), antibonding orbitals form.

Final answer:

Molecular orbital theory describes the behavior of electrons in a molecule in terms of combinations of atomic wave functions. The resulting molecular orbitals may extend over all the atoms in the molecule. Bonding molecular orbitals are formed by in-phase combinations of atomic wave functions, and electrons in these orbitals stabilize a molecule.

Step-by-step explanation:

Molecular orbital theory describes the behavior of electrons in a molecule in terms of combinations of the atomic wave functions. The resulting molecular orbitals may extend over all the atoms in the molecule. Bonding molecular orbitals are formed by in-phase combinations of atomic wave functions, and electrons in these orbitals stabilize a molecule. Antibonding molecular orbitals result from out-of-phase combinations of atomic wave functions and electrons in these orbitals make a molecule less stable. Molecular orbitals located along an internuclear axis are called o MOS. They can be formed from s orbitals or from p orbitals oriented in an end-to-end fashion. Molecular orbitals formed from p orbitals oriented in a side-by-side fashion have electron density on opposite sides of the internuclear axis and are called orbitals.
