Question

Dalton’s atomic theory was based on:

• A. Law of chemical combination
• B. Mass theory
• C. Periodic table
• D. None of the above

Answer 1

The correct option is A Law of chemical combination

When substances react, they do so by following certain laws. These laws are called the laws of chemical combination. Law of conservation of mass, the law of definite proportions, the law of multiple proportions, Gay lussac's law of gaseous volumes, Avogadro's law. These formed the basis of Dalton's atomic theory of matter.

Dalton explained about atoms on the basis of the Laws of Chemical Combinations.

So, the correct option is $A$.
