Graphite - network solid
Ammonium phosphate - ionic
Brass - metallic
SiC - network solid
Rb- metallic
I2 - molecular
LiBr- ionic
P4 - molecular
Plastic - amorphous
Si - network
Explanation:
An ionic solid is consists of a combination of two oppositely charged ions to yield a crystal lattice such as LiBr.
A covalent solid is one in whom the atoms of the molecule are held together by covalent bonds e.g I2.
Metals are held together by interaction of metal ions and a sea of electrons. This is called the metallic bond. Like SiC
A network solid consists of covalently bonded atoms held together by strong covalent bonds and the molecules in the solid state are held together by a continuous network of atoms.
