SureDenTypes of Solids
A solid is that state of matter in which its constituent atoms or molecules are held strongly at the position of minimum potential energy and it has a definite shape and volume. The solids can be classified into two categories, crystalline and glassy or amorphous solids.

The constituent atoms, ions or molecules are arranged in a regular repeated three dimensional pattern, within the solid. |
