Concept introduction:
All matter can exist in mainly three states; solid, liquid and gases. Here, solids can be further classified in different types based on their structural units. The structural units can be constituent atoms or molecules or ions. Such as ionic solids are composed of ions, whereas metallic solids are composed of metal ions and electrons. A covalent solid consists of covalent molecules in it. Hence, one can easily identify the structural units with the help of type of solids and vice-versa.
