Question

1. which of these statements, later proven incorrect, 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 can only change into atoms of another element through nuclear reactions. atoms are the smallest particles of matter and cannot be divided farther. atoms of a particular element all have the same number of protons.

Explanation:

Dalton's atomic theory stated that atoms are the smallest particles of matter and cannot be divided. However, later discoveries such as sub - atomic particles (protons, neutrons, electrons) proved this incorrect. Also, the idea that atoms of a particular element all have the same number of protons is correct, atoms can change into atoms of another element through nuclear reactions, and there is no relation in Dalton's theory about the mass comparison of atoms in different states of matter (gases, liquids, solids) as described in the first option.

Answer:

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