Gr 11 Physical Sciences: Ch 3.4 Energy and bonding

What occurs when atoms move closer than the bond length?

The bond energy is released, and the bond breaks
The bond length is established, and the bond forms
Attractive forces dominate, increasing the bond energy
Repulsive forces dominate, increasing the system's energy (correct)

What is represented by the bond energy?

The energy released when a bond breaks
The energy difference between the bonded state and the state where atoms are far apart (correct)
The minimum energy point where the bond forms
The energy required to form a bond

At what point do attractive and repulsive forces balance?

When the atoms are far apart
When the bond breaks
At the minimum energy point (correct)
When the bond energy is released
