Ionic 1 of 11 What type of chemical boning is found in substances with non metal atoms only? Covalent 2 of 11 What type of chemical bonding is fond in gold? Metallic 3 of 11 Explain why ionic substances have high melting points and boiling points Strong forces of attraction require a lot of energy to break 4 of 11 Explain why ionic substances do not conduct electricity when solid but do conduct energy when molten or dissolved in solid-state ions are fixed and cannot move in molten state ions are able to moved carry electrical charge 5 of 11 Explain why simple covaelent structures have low melting and boiling points weak intermolecular forces between separate molecules 6 of 11 Explain why simple covalent substances do not conduct electricity no ions/ free electrons cannot carry electrical charge 7 of 11 Explain why diamonds are strong and hard Strong covalent bonds no weak forces requires a lot of energy to break 8 of 11 Explain why graphite is a conductor of electricity Free electrons can move 9 of 11 Define the term nano particle Tiny particle of a substance 10 of 11 State 2 advantages and 2 disadvantages of using nano materials Designer material, large surface area, toxicity, harmful to the environment 11 of 11
