Question

Explain the formation of H2 molecules on the basis of valence bond theory​

Answer 1

Answer:-

According to valence bond theory "An atom with unpaired electron tends to form bond with other atom having unpaired electrons so that both of them acquire stable noble gas configuration"

H atom has one single electron in its 1s orbital,so its electronic configuration is 1s1.

Two H atoms come together and shair their single electron electrons to form a single bond.

Explain the formation of H2 molecules on the basis of valence bond theory​

Answer :
_______


When hydrogen atoms combine to form molecules of hydrogen 433 KJ/mol energy is released.

Whenever atoms combine to form a molecule ,there is always decrease in the energy.

The nuclei of the atoms as well as their electrons repel each other.
