Solution Summary: The author explains that Molecular orbit theory is more accurate than valence bond theory. Waves with same phase will interfere constructively and increase their amplitude.
Definition Definition Theory that explains how individual atomic orbitals with an unpaired electron each, come close to each other and overlap to form a molecular orbital giving a covalent bond. VBT gives a quantum mechanical approach to the formation of covalent bonds with the help of wave functions using attractive and repulsive energies when two atoms are brought from infinity to their internuclear distance.

Interpretation Introduction
Interpretation:
Molecular orbit theory is more accurate theory than valence bond theory. In molecular orbital theory,we imagine that electronic orbitals cover the whole molecule and are not localised around one atom. Molecular orbital theory is based on wave superposition principle. Waves with same phase will interfere constructively and increase their amplitude. While opposite phases interfere destructively to decrease their amplitude.
Concept introduction:
From above it becomes clear that no of atomic orbital is equal to molecular orbital.
No of atom in the given sample
Each sodium atoms have one atomic orbital so no. of atomic orbital in the given sample of sodium is equal to the no. of atom,
No. of molecular orbital in given sample is equal to no. of atomic orbital in given sample as from the above diagram
To determine: the no. of molecular orbitals present in the valence band of a sodium crystal with a mass of
These are in the wrong boxes. Why does the one on the left have a lower molar mass than the one on the right?
SYNTHESIS REACTIONS. For the following reactions, synthesize the given products from the given reactants.
Multiple reactions/steps will be needed. For the one of the steps (ie reactions) in each synthesis, write out the
mechanism for that reaction and draw an energy diagram showing the correct number of hills and valleys for
