Question

What did Dalton discover about the atoms that combine to form compounds?

Answer 1

Dalton discovered that atoms that combine to form compounds are differentiated by their atomic weights.

Answer 2

Step-by-step explanation:

Dalton's theory states that every matter is comprised of very small particles called atoms.

All these atoms of same element are similar in size, mass and other properties. Whereas different elements have atoms of different size, mass, and other properties.

Dalton discovered that atoms are indivisible in nature, and they cannot be created or destroyed. Theses are the smallest entities which participate in a chemical reaction.
