Based on the Molecular Orbital theory, the idea of combining atomic orbitals to make molecular orbitals (Linear Combination of Atomic Orbitals, LCAO), if two atomic orbitals are combined to make Molecular Orbitals, they will combine in two different ways and make two different Molecular Orbitals. Explain the two different ways they would combine and indicate the type of orbital formed from each different way of combining. For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).
