COVALENT STRUCTURES

HideShow resource information
Which structure do all ionic compounds form?
Giant Structures
1 of 10
Why do they have high melting and boiling points?
strong forces of attraction between oppositly charged ions
2 of 10
Why can ionic substances conduct when they are molten?
ions can move
3 of 10
Why can ionic substances conduct electricity when dissolved but not when they are solid?
when dissolved the ions can move
4 of 10
Give an example of a simple molecular substance.
chlorine/oxygen/hydrogen iodide/water
5 of 10
In simple molecular compounds describe the bonding between atoms and between molecules.
strong attraction between atoms,weak between molecules
6 of 10
Can simple molecular compounds ever conduct electricity?
No
7 of 10
Give two forms of carbon which are giant covalent substances.
diamond and graphite
8 of 10
Why do giant covalent substances have high melting and boiling points?
strong covalent bonding through the structure
9 of 10
Why can graphite conduct electricity?
bonding between the layers is weak and these electrons conduct electricity
