A molecular compound is formed when a chemical reaction occurs between atoms of

the reaction mechanism occurs by electrostatic attraction of some type, where electrons are shared or transferred into the atoms and the new molecular compound is established more betabel than the indigenous atoms

Explanation:

Molecules are formed by atoms, through those of many chemical reactions that are processes by which the energy of the products is less than the energy of the reactants.

In these processes, in general, the reaction mechanism occurs by electrostatic attraction of some type, where electrons are shared or transferred into the atoms and the new molecular compound is established more betabel than the indigenous atoms
