Introduction
John Dalton law was proposed by John Dalton in the year 1801. According to this law at a particular temperature, the total pressure of a mixture of two or more non-interacting gases is equal to the sum of partial pressures of the individual gases.
This law can be mathematically written as:
Ptotal = P1 + P2 + P3 + ...
Here P1, P2, P3 are the partial pressures of each component in the mixture.
John Daltons Atomic Theory, Laws of multiple proportions, Dalton’s law of partial pressure and for Daltanism. Dalton concluded that evaporated water exists in air as an independent gas in the course of his studies. Dalton found that evaporation might be viewed as a mixing of water particles with air particles. He performed a series of experiments on mixtures of gases to determine what effect properties of the individual gases had on the properties of the mixture as a whole and he was the first to associate the ancient idea of atoms with stoichiometry. Dalton came to know the vital theoretical connection between atomic weights and weight relations in chemical reactions. The core concepts of Dalton’s theory are foundations of modern physical science.

Atoms are indestructible and unchangeable: According to this assumption of John Dalton atoms of an element cannot be created, destroyed, broken into smaller parts or transformed into atoms of another element. So he stated that atoms cannot be created, destroyed or transformed into other atoms in a chemical change.
Elements are characterized by the mass of their atoms: According to this assumption atoms of different elements have different weights.
When elements react their atoms combine in simple, whole number ratios: In this postulate Dolton explained that compounds contained characteristic atom-to-atom ratios in this postulate he effectively explained the law of definite proportions.
When elements react, their atoms sometimes combine in more than one simple, whole-number ratio: According to this postulate why the weight ratios of nitrogen to oxygen in various nitrogen oxides were themselves simple multiples of each other.

Assumptions of John Dolton chemistry
All matter consists of tiny particlesAtoms are indestructible and unchangeable: According to this assumption of John Dalton atoms of an element cannot be created, destroyed, broken into smaller parts or transformed into atoms of another element. So he stated that atoms cannot be created, destroyed or transformed into other atoms in a chemical change.
