Matter

Anything that exhibits inertia is called Matter. The quantity of Matter is its Mass.

Everything in the world that has some mass and holds some space is being referred to as Matter.

Matter exists in three different physical forms including Solid, Liquid, and Gas.

Property Solid Liquid Gas
Tightness They are tightly packed Tightly packed Loosely packed
Intermolecular Space Low Medium High
Force of Attraction Maximum Medium Low
Kinetic Energy Minimum Medium High
Density High Medium Low
Volume Some Fixed Variant
Shape Fixed Variable Variable
Compressibility Factor Minimum Medium Maximum

Elements:

 \to It is the simplest form of Matter.

 \to Smallest unit of an element is known as Atom.

 \to Total number of the known elements is  118 out of which  98 elements occur naturally and  20   are formed by artificial transmutation.

\to e.g.   \text { Na, K, Mg, P, C, F } etc.

\to These are further classified into : Metal, Non-Metal and Mettaloids.

Compound:

\to  It is a non-elemental pure compound.

\to Formed by chemical combination of two or more atoms of different elements in a fixed ratio.

\to e.g.,  H_2O, CO_2, C_8H_{12}O_6, NO_2, NH_3 etc.

Mixture:

 \to Formed by Physical Combination of two or more Pure Substances in any ratio.

\to Chemical Identity of the Pure Components remains maintained in mixtures.

\to Homogenous Mixtures are those whose composition for each part remains constant.

E.g Aqueous &  Gaseous solution.

 \to Heterogeneous Mixtures are those whose composition may vary for each and every part.

E.g. Soil & Concrete Mixtures.
