Question

give the postulates of Dalton's atomic theory​

Answer 1

1.all matter is made up of indivisible particles called atoms

2.mass neither created nor destroyed ,chemical reactions only change the composition of the compounds

3.elements react in different different ratio to form different different compounds

eg:-1.CO2(1:2)

2.CO(1:1)

4.In chemical reaction mass neither created nor destroyed and mass of reactants = mass of products.

Answer 2

Postulates of Dalton's atomic theory:

• All matter consists of indivisible particles called atoms.
• Atoms of the same element are similar in shape and mass, but differ from the atoms of other elements.
• Atoms cannot be created or destroyed.
• Atoms of different elements may combine with each other in a fixed, simple, whole number ratios to form compound atoms.
• Atoms of same element can combine in more than one ratio to form two or more compounds.
• The atom is the smallest unit of matter that can take part in a chemical reaction.
