What is atomic model in chemistry?

What is Dalton's model?

Dalton’s atomic model given the primary basis of chemistry and today this model grows up by discovering the electron cloud model.

All the chemical reactions in chemistry clearly explained by this model.

  1. Matter made of atoms is indivisible and indestructible.
  2. All the atoms of a given element are identical mass and properties.
  3. Compounds formed by the combination of two or more same or different kinds of atoms.
  4. A chemical reaction is a rearrangement of atoms.

But Dalton’s model of indivisibility of atom discarded by the discovery of various elementary particles like proton, neutrons, and electrons.

Modern atomic theory

The modern structure of an atom Rutherford has remarked that it is not in the nature of things for any one man to make the sudden violet discovery.

Science goes step by step and every man depends on the work of his predecessor. The journey from Dalton’s model to the modern structure of an atom was a long and arduous one.

This century much valuable information was being compiled. This study clearly indicates that Dalton’s atomic model no longer enjoyed the exalted position to grant it.

Today an atom considered to made up of a tiny nucleus carrying neutrons and protons.

Structure of atom

The nucleus of an atom has around itself a certain number of the negatively charged particles carrying negligible mass, called electrons, arranged in a definite order.
