Diamond crystals are:
Octahedral in shape and are giant metallic crystals.
Octahedral in shape and are giant atomic crystals.
Tetrahedral in shape and are giant atomic crystals.
Octahedral in shape and are giant ionic crystals.
Carbon tetrachloride is not hydrolysed by water but silicon tetrachloride is readily hydrolysed in water.
This is because:
Silicon does not possess low lying vacant d-orbitals.
Carbon cannot expand its octet.
Carbon does not possess low lying vacant d-orbitals.
Silicon has a lower melting point than carbon.
Diamond has a very high melting point and is resistant to chemical attack due to:
The strength of the metallic bonds in its crystals lattice.
The strength of the covalent bonds in its crystals lattice.
The strength of the covalent and ionic bonds in its crystals lattice.
The strength of the dative covalent bonds in its crystals lattice.
Inert pair effect:
Increases as you move down the group 14 elements.
Decreases as you move down the group 14 elements.
Increases and then decreases as move down the group 14 elements.
Does not change as you move down the group 14 elements.
The ability of a group 14 elements to form strong covalent bonds with itself by forming chains and rings is called?
Catenation.
Strong bonding.
Hybridisation.
Inert pair effect.
