Read through the full deck, or practise recalling each answer above.
How many covalent bonds does each carbon atom form in diamond?
Show answer
Four — each carbon atom is bonded to four other carbon atoms.
What type of structure does diamond have?
Show answer
A giant covalent structure of carbon atoms.
In diamond, each carbon atom forms ? covalent bonds with other carbon atoms.
Show answer
four
Why is diamond very hard?
Show answer
Each carbon atom is held by four strong covalent bonds in a rigid giant covalent lattice.
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.
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.
Diamond does not conduct ? because it has no free electrons.
Show answer
electricity
Which element makes up diamond?
Show answer
Carbon.
Diamond
Show answer
A giant covalent structure in which each carbon atom forms four covalent bonds with other carbon atoms.
