level questions: Covalent Bonds
| Question | Answer |
|---|---|
| Why are covalent bonds strong | The shared electrons are attracted to the nucleus of both atoms |
| Give me an example of a small covalent molecule | water, nitrogen, hydrogen, chlorine |
| How do we represent covalent bonds | Dot and cross diagram |
| Double and triple covalent bonds | Stronger than single bond and require more energy to break |
| Name the 3 other ways of representing covalent bonds | Lines, ball and stick, dot and cross without shells |
| What is a limitation of ball and stick | Atoms are much closer together than the diagram shows |
| What is a limitation of the dot and cross with shells | Shows electrons differently when they are all the same |
| Explain how a covalent bond holds two atoms together. | electrostatic force of attraction between shared negatively charged electron and positive nuclei |
