Answer:
1) All matter is made of atoms. Atoms are indivisible and indestructible. 2) Allatoms of a given element are identical in mass and properties. 3) Compounds are formed by a combination of two or more different kinds of atoms.
2. Dalton based his theory on the law of conservation of mass and the law of constant composition. The first part of his theory states that all matter is made of atoms, which are indivisible. The second part of the theory says all atoms of a given element are identical in mass and properties.
3. The matter is made up of indivisible particles known as atoms. ... Atoms of different elements combine in fixed ratios to form compounds. Atoms are neither created nor destroyed. This implies that during chemical reactions, no atoms are created nor destroyed.

Answer:
Drawbacks of Dalton's Atomic Theory. The indivisibility of an atom was proved wrong: an atom can be further subdivided into protons, neutrons and electrons. However an atom is the smallest particle that takes part in chemical reactions. According to Dalton, the atoms of same element are similar in all respects
