In a solid, the particles pack together as tightly as possible in a neat and ordered arrangement. The particles are held together too strongly to allow movement from place to place but the particles do vibrate about their position in the structure.

Metals have relatively high melting points. This explains why all metals except for mercury are solids at room temperature. Most metals are good conductors of heat. That's why metals such as iron, copper, and aluminum are used for pots and pans.

A crystal is a substance in which the particles are arranged in an orderly, geometric, repeating pattern.

Some solid materials have no regular internal patterns. Glass is a solid that consists of densely packed atoms arranged randomly. Glasses form when molten material is chilled so rapidly that atoms do not have enough time to arrange themselves in a regular pattern.

in a solid the arrangement of particles are fixed and closely packed and the movement is they vibrate in place. A liquids arrangement of particles is closely packed and takes shape of container and the movement is it moves freely around one another.

Crystalline solids have regular ordered arrays of components held together by uniform intermolecular forces, whereas the components of amorphous solids are not arranged in regular arrays.

In a crystal, the particles are arranged in an orderly, repeating, three-dimensional pattern called a crystal lattice.
