Question 8

Name 4 properties Of ionic and covalent bonding

Answer 8

Ionic -

1) high melting and boiling points
2) do not conduct electricity when boiling
3) when dissolved in water or melted it conducts electricity
4) a lot of energy is needed to brake bond

Covalent

1) low melting low boiling
2) don’t conduct electricity
3) usually gases or liquids
4) bonds within covalent molecules are very strong
