How many bonds does each carbon have in diamond?

• 2

• 4

• 6

• 8

Explain why diamond has a high melting point

• Giant structure, strong covalent bonds between the atoms, requires a lot of energy to break

• Giant structure, weak covalent bonds between the atoms, requires little energy to break

• Mega structure, strong covalent bonds between the atoms, requires a lot of energy to break

• Mega structure, weak covalent bonds between the atoms, requires little energy to break

Explain why most giant covalent substances do not conduct electricity.

• There are no electrons/ions/charged particles that are free to move

• The electrons/ions/charged particles that are free to move

• The electrons/ions/charged particles cannot carry the charge

• There are not enough electrons/ions/charged particles to carry the charge through the structure
