Question

All of the following are assumptions presented by Dalton's atomic theory except that

A. atoms combine with other atoms.

B. all atoms of different elements are alike in size, shape, and weight.

C. all matter consists of atoms.

D. atoms don't break into pieces even during chemical reactions.

Answer 1

B. all atoms of different elements are alike in size, shape, and weight.

Step-by-step explanation:

All matter is composed of atoms

Atoms of a given element are identical in size, mass, and other properties.

Atoms cannot be subdivided, created, or destroyed.

Atoms of different elements can combine in simple, whole ratios to form chemical compounds.

In chemical reactions, atoms are combined, separated, or rearranged.
