What is a compound, definition of a compound (What Is Compound In Hindi)

Mixture

The substances formed by mixing two or more substances in any ratio are called mixtures. Their composition is not fixed.

Their properties are a combination of the properties of the ingredients of the mixture. The components of a mixture can be separated by simple physical methods. Mixtures are often विषमांग (heterogeneous) And its physical constants such as melting point, boiling point, density etc. are constant and not fixed.

There are two types of mixture (Type of mixture in hindi)

(i) Homogeneous Mixture

The composition of any part of them is the same as the composition of any other part of it. Example aqueous solution of sugar.

(ii) Heterogeneous Mixture

The composition of their different parts is different from each other. Each of its components exhibits its own characteristics. Example a mixture of sand and salt.

compound in hindi

These are two or more elements in a certain ratio chemical combination is made from. Their composition is fixed. Their properties are different and definite from the constituent elements. The components of a compound cannot be separated by physical methods. Compounds are homogeneous and their physical constants like-Melting point, boiling point, density etc. are fixed and fixed.

Atom and Molecule

Atom

An atom is that very fine particle of an element, which cannot exist in its free state, but can take part in a chemical reaction.

Molecule

Molecule is the smallest particle of an element or compound that can exist in a free state, but does not take part in a chemical reaction (but its constituents participate). All the properties of that element or compound are present in the molecule.

Molecules and atoms are the main components of matter. Atoms combine to form molecules. Molecules are of following types on the basis of number of atoms.

(a) Monoatomic molecule They contain one atom. Example Na, K etc.

(b) Diatomic molecule They have two atoms. Example O2, Cl2, N2, etc.

(c) Triatomic molecule) contains three atoms. Example O3, etc.

(d) Polyatomic molecule They contain more than three atoms. Example P4, S8 etc. The number of atoms present in the molecules of an element or compound is called its atomicity.
