6. High
7. Crystalline
8. Lattice
9. Unit cell
10. Amorphous solids

Explanation:

Solids tend to be dense and difficult to compress.

They do not  flow or take the shape of their containers, like liquids do, because  the particles in solids vibrate around fixed points.

When a solid  is heated until its particles vibrate so rapidly that they are no longer  held in fixed positions, the solid melts.  

Melting point is the  temperature at which a solid changes to a liquid. The melting and freezing point  of a substance are at the same temperature.

In general,  ionic solids tend to have relatively high  melting points, while  molecular solids tend to have relatively low melting points.

Most  solids are crystalline

The particles are arranged in a pattern known  as a crystal lattice

The smallest subunit of a crystal lattice is the unit cell  

Some solids lack an ordered internal structure   and are called amorphous solids.
