Why does nature favor chemical bonding?

Because it leads to the formation of diatomic molecules

Because it leads to lower potential energy for individual atoms (correct)

Because individual atoms are more stable when not bonded

Because it results in higher potential energy for individual atoms

What is the main reason for the formation of diatomic molecules?

To increase the potential energy of the individual atoms

To decrease stability of the individual atoms

Because the molecules formed are less stable than the individual atoms

Because the molecules formed are more stable than the individual atoms (correct)

What happens as two atoms approach each other to form a covalent bond?

The attractive forces balance the repulsive forces (correct)

The repulsive force between protons increases

The attractive force between protons and electrons decreases

The repulsive force between electrons decreases
