Question #0504b

Answer 1

Ans:E

Explanation:

Electrostatic potential energy `U=K(q_1q_2)/(r)`{(`K=(1)/(4piepsilon_0)`}

Atoms combine to forms molecules and the energy of the molecules is lower that the individual atoms and thus that molecule is stable. This happens because the free atoms combine and release energy at the process of bond formation.
