| 1 | Why? What are the bonds? | |
| 2 | A molecule is a group of atoms held together by chemical bonds. | |
| 3 | Same bond, symmetric bonds means equal energy, which means equal links. | |
| 4 | So strong bonds means high melting points and boiling points. | |
| 5 | The strength comes from the powerful chemical bonds that form between carbon atoms (think diamond). |
