Question

what are the limitations of daltons atomic theory ?,​

Answer 1

Drawbacks of Dalton's Atomic Theory:

Drawbacks of Dalton's Atomic Theory: 1. The atom is further subdivided into protons, neutrons and electrons.

Drawbacks of Dalton's Atomic Theory: 1. The atom is further subdivided into protons, neutrons and electrons. 2. The atoms of same elements are not similar in all respect. They may vary in mass and density. These are known as isotopes. For example: chlorine has two isotopes having mass numbers 35 a.m.u and 37 a.m.u.

Atoms of different elements are not different in all respects. Atoms of different elements that have the same atomic mass are called isobar.

Atoms of different elements are not different in all respects. Atoms of different elements that have the same atomic mass are called isobar. 4. According to Dalton atoms of different elements combine in simple whole number ratio to form compounds. This is not seen in complex organic compounds like sugar C12H22O11.

The theory fails to explain the existence of allotropes.

Answer 2

Answer:

Limitations of Dalton's Atomic Theory:

1) Atom consists of particles like electrons, protons, and neutrons but Dalton says atoms are indivisible and they can neither be created nor be destroyed.

2)Discovery of isotopes revealed that the atoms of the same element possess different weights.
