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
