  1. How many covalent bonds does each carbon atom form in diamond?

    Show answer

    Four — each carbon atom is bonded to four other carbon atoms.

  2. What type of structure does diamond have?

    Show answer

    A giant covalent structure of carbon atoms.

  3. In diamond, each carbon atom forms ? covalent bonds with other carbon atoms.

    Show answer

    four

  4. Why is diamond very hard?

    Show answer

    Each carbon atom is held by four strong covalent bonds in a rigid giant covalent lattice.

  5. Why does diamond have a very high melting point?

    Show answer

    Many strong covalent bonds throughout the giant structure must be broken, which requires a lot of energy.

  6. Why does diamond not conduct electricity?

    Show answer

    All four outer electrons of each carbon atom are used in covalent bonds, so there are no free (delocalised) electrons to carry charge.

  7. Diamond does not conduct ? because it has no free electrons.

    Show answer

    electricity

  8. Which element makes up diamond?

    Show answer

    Carbon.

  9. Diamond

    Show answer

    A giant covalent structure in which each carbon atom forms four covalent bonds with other carbon atoms.
