Topic 4: Chemical bonding
3. Bonding and energy: Recalling concept facts and definitions
1. When a bond is formed between two atoms, the stability of the atoms
1) Increases 2)Decreases 3) Remained the same
2. As a bond is formed between atoms, potential energy of the atoms generally
1) Decreases
2) Increases
3) Remains the same
3. When a bond is broken in a chemical substance, the stability of the atoms
1) Remained the same 2) Decreases 3) Increases
4. As a bond is broken in a compound, the potential energy of the atoms generally
1) Remained the same 2) Decreased 3) Increased

8. When a bond is broken in compounds, energy is generally 3) Both released and absorbed
1) Released
2) Absorbed 4) Neither released not absorbed
9. When two atoms form a bond to produce a chemical substance, the stability of the chemical
system
1) Decreases as energy is absorbed 3) Increases as energy is absorbed
2) Decreases as energy is released 4) Increases as energy is released
10. When a bond is broken in a chemical substance, the stability of the chemical system
1) Decreases as energy is absorbed 3) Increases as energy is absorbed
2) Decreases as energy is released 4) Increases as energy is releases
11. What type of energy is stored in the bonds of chemical substances?
1) Kinetic energy
3) Activation energy
2) Potential energy 4) Ionization energy
12. The amount of potential energy in chemical bonds of substances depends on
1) The composition of the chemical substances only
2) The structure of the chemical substances only
3) Both the composition and the structure of chemical substances
4) Neither the composition nor the structure of chemical substances
