Answer:explanation of Valence bond theory in terms of energy
Eg:formation of Hydrogen
If the two hydrogen atom are far apart from each other then its energy is equal to zero.
When these hydrogen atoms approaches to each other with its half filled orbital, then there is a force of attraction between nucleus of an atom and electron of other atom and vice versa.And also repulsion between nucleus of two atoms and also repulsion between electrons of two atoms.When these two Hydrogen atoms are close to each other then force of attraction overcome force of repulsion. As a result, at the midpoint of internuclear axis overlapping of half filled orbital take place.Thus a covalent bond is forned between hydrogen atoms.
