Question

1. which of these statements is one of the conclusions that formed the basis of daltons atomic theory? atoms of gases have less mass than atoms of liquids and solids. atoms of a particular element all have the same number of protons. atoms can only change into atoms of another element through nuclear reactions. atoms are the smallest particles of matter and cannot be divided farther.

Explanation:

Dalton's atomic theory proposed that atoms are the smallest indivisible particles of matter. The concept of protons and nuclear reactions came later. Also, Dalton did not compare the mass of atoms in different states (gases, liquids, solids) in his theory.

Answer:

Atoms are the smallest particles of matter and cannot be divided farther.
