Why does Cl have a low boiling point? | Van Der Waals forces of attraction/ intermolecular forces are weak. Little energy is required to break this bonds. |
Ionic compounds have high melting points. | `Oppositely charged ions are very strong. Huge amount of energy is required to break bonds. |
Metals are good electrical conductors. | Mobile ions move freely between the positively charged metal ions. |
Graphite is soft. | Carbon atoms are weak. The layers can slide over each other easily. |
Diamond does not conduct electricity. | They consist of atoms and there are no free electrons remaining to conduct electricity. |
