Answer:
A. The atoms have more energy together than separated.
Explanation:
There are several reasons why a chemical bond could take place. Adding things like heat or pressure stimulate the atoms to force a reaction to take place. But when it comes down to it, the intramolecular forces of the electrons pull each other to form chemical bonds (represented by Valence electrons). The stronger these are, the more likely they are going to bond.
Atoms with lower forces typically don't typically bond with other atoms of lower forces.
