What is the atomic theory of Dalton and its limitation
Answers
Answer:
1) All matter is made up of extremely small and indivisible particles called atom.
2) Atoms of the same element are identical in all respect that at is size, shape, mass and properties.
3) Atoms of different elements have different size and masses and posses different properties
4) Atoms of the same or different element combined together their in fixed proportion and form molecule or compound.
5)The number and kind of atoms in a given compound is always fixed.
6) Atom is the smallest particle that can take part in a chemical reaction.
7) Atom can neither be created nor be destroyed.
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.
