Q
Ionic compounds form a
A
lattice structure
2
Q
An ionic lattice is a regular arrangement of
A
metal and non-metal ions
3
Q
A lattice structure creates compounds with a
A
high melting point which conduct when molten or in solution.
4
Q
Lattice structure compounds never conduct when
A
solid
5
Q
Ionic compounds dissolve in water very
A
easily
6
Q
When ionic compounds are dissolve their ions are
A
free to move and carry the electrical charge.
7
Q
Covalent network substance have a
A
very high melting point and are very hard because of their strong bonds
8
Q
Covalent molecules such as oxygen and water have
A
low melting and boiling points
9
Q
Covalent compounds do not
A
conduct electricity except water.
10
Q
EXCEPTION: Graphite is a covalent network that does conduct because
A
it has delocalised electrons
