Answer:
Both decrease the energy of the atomic orbitals to form the molecule by their overlap
Explanation:
Many molecules are not described correctly by Lewis theory. For example, diborane (B2H6), which is an electrodeficient compound: there are not enough valence electrons to be able to assign a Lewis structure.
The theory of binding and anti-binding orbitals describes molecular orbitals, whose atomic orbitals overlap to form them. Two atomic orbitals overlap giving a binding orbital molecular orbital. In the binder, the electrons that occupy it have a high possibility of being located between the atoms, so filling stabilizes the molecule. In an anti-binding orbital, the electrons that occupy it have a low probability of being located between the atoms, so that their filling destabilizes the molecule.
The interaction between two atomic orbitals is greater the greater their overlap and the smaller their energy difference.

Allright for <span><span>H2</span>O:</span>
- The central atom is? --> the oxygen atom
- How many atoms are bonded to the central atom? --> 2 hydrogen atoms
- How many lone pairs of electrons are on the central atom? --> O has 6 electrons and has 2 single bonds, so 2 pairs
- How many single bonds are there in this molecule? --> 2
- How many multiple bonds (double and/or triple) are there in this molecule? --> none
For each of your molecules, answer the following questions:
1. Determine the electronegativity between the atoms of each molecule.
Electronegativity O = 3.44
Electronegativity H = 2.20
3.44-2.20=1.24, so the electronegativity between O and H = 1.24
2. Identify the bond as either ionic or covalent.
Electronegativity of 0.0-1.7 = covalent
Electronegativity of 1.7-3.3 = ionic
So it's a covalent bond
3. State whether the molecule is polar or non polar.
Electronegativity of 0.5-1.7= polar covalent
4. Identify the structure as having hydrogen bonding, dipole-dipole moments or London dispersion forces (LDF).
