Answer;

P4O10 - molecular solid

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.
