Question

How many molecular orbitals can be built from the valence shell orbitals in o2?

Answer 1

We can calculate the bond order in the O2 molecule by noting that there are eight valence electrons in bonding molecular orbitals and four valence electrons in antibonding molecular orbitals in the electron configuration of this molecule. Thus, the bond order is two.

Answer 2

How many molecular orbitals can be built from the valence shell orbitals in o2?

Explanation:

• Ernest Z. O₂ has an infinite number of molecular orbitals, but only nine of them are occupied in the ground state.
• Each oxygen bonds to the other with its 1s, 2s, and 2p orbitals.
• These 5 atomic orbitals combine to form 10 molecular orbitals. These 10 MOs have capacity to accommodate up to 20 electrons, each oxygen atom will contribute 8 electrons.
• Each O atom contributes 8 electrons to the O₂ molecule.
