Question
Explain the Dalton's Atomic Theory postulates in points, class 9 atoms and molecules
Solution
Dalton's Atomic Theory is a fundamental concept that explains the nature of matter. The theory was proposed by John Dalton, a British scientist in the early 19th century. Here are the postulates of Dalton's Atomic Theory:
-
Elements are made of extremely small particles called atoms. Atoms are indivisible and indestructible.
-
All atoms of a given element are identical in mass and properties.
-
Compounds are formed by a combination of two or more different kinds of atoms.
-
A chemical reaction is a rearrangement of atoms.
-
Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process; a chemical reaction simply changes the way atoms are grouped together.
These postulates form the basis of our understanding of the structure of matter and the nature of chemical reactions. However, with the advent of modern physics and quantum mechanics, some of these postulates have been refined. For example, we now know that atoms can indeed be split into smaller particles (protons, neutrons, and
