Answer:
True
Explanation:
In Dalton’s initial atomic theory he believed, matter is made of atoms, which are indivisible. This is statement is now rejected because modern technology allowed scientists to notate that atoms can be subdivided into protons, neutrons, and electrons. However, atoms are the smallest particles that takes part in chemical reactions. According to Dalton, the atoms of same element are similar in all respects. The second part of the theory says all atoms of a given element are identical in mass and properties. The periodic table disproves this entire belief by conveying that each element has its own mass number and properties (different atomic numbers). With these two being disproved, we no longer approve of his theories.
