Why does Cl have a low boiling point? | Weak van der waals forces of attraction, little energy is required to break these bonds. |
Why does ionic compounds have higher boiling points? | Electrostatic forces are made up of oppositely charged ions are very strong. Huge amount of energy is needed to break these bonds. |
Why are metals good electrical conductors? | Mobile ions move freely between the positively charged metal ions |
Why is graphite is soft? | Carbon atoms are weak and the layers can slide easily over one another. |
Why is diamond unable to conduct electricity? | Electrons for bonding with other carbon atoms , so no free electrons remaining to conduct current |
