Interpretation Introduction

Interpretation:

The type of solid formed by the given by compounds has to be identified.

Concept introduction:

Solids constitute the major part of the matter in the universe. Beneath the earth as well as above the sky in our Universe, and in our everyday life, solids can be found. Solids do have such a profound significance since the beginning of the Universe and human evolution.

A solid is anything that is firm and stable in shape. Physics and Chemistry do provide clear cut explanation for the structure of solids. The firm and dense nature of solids is due to the strong intermolecular forces between their components.

On the basis of the arrangement of the components in a solid, there are two distinct types of solids - crystalline solids and amorphous solids. These two types differ in the arrangement of their respective components and so in their properties.

Crystalline solids have their own sub-classification. The types of solids can be summarized as follows –

Figure 1

Crystalline solids have well-defined regular, compact, orderly arrangement of their components in a very long range order. They are termed as true solids.

Amorphous solids lack such well defined arrangement of its components thus disordered or random arrangement does exist in them. They are termed as pseudo solids orsuper cooled liquids.

Ionic solids, molecular solids, covalent solids and metallic solids are the types of crystalline solids.

In ionic solids, ions of opposite charges are bind together by electrostatic force and are neatly stacked to form a regular and well-defined structure.

If molecules are arranged in such a fashion, then it is molecular solid whereas metal atoms are arranged in such a manner, it is metallic solid. Non-metal atoms held together by weak London dispersion forces form atomic solids.

In Covalent solids the components are atoms bonded by covalent bond repetitively and thus forms huge network form of solid. It is also known as atomic network solids. They are widely formed by group 14 elements and its compounds.

All these types of solids differ in their respective intramolecular as well as intermolecular forces.
