Explain about the Dalton atomic theory.
Answers
Answer:
Dalton Atomic theory :
In 1808, an English school teacher named John Dalton proposed an explanation for the law of conservation of mass, the law of definite proportions, and the law of multiple proportions.
The main points of his theory are:
1. All mater is made up of extremely small particles called ''Atoms''.
2. Atoms of same element are identical in size, mass and other properties atoms of different elements differ in size, mass and other properties.
3. Atoms cannot be created or destroyed.
4. Atoms of different elements combine in simple whole number ratios to form chemical compounds.
5. Atoms are the smallest particles but they will take part in the chemical reaction.
Answer:
Explanation:
Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties. ... The first part of his theory states that all matter is made of atoms, which are indivisible. The second part of the theory says all atoms of a given element are identical in mass and properties.
