# What is the difference between atomic model of Rutherford and Thomson?

## What is the difference between atomic model of Rutherford and Thomson?

The key difference between Thomson and Rutherford model of atom is that Thomson model of atom does not contain any details about nucleus whereas Rutherford model of atom explains about the nucleus of an atom. J.J. The model he proposed was named as ‘plum pudding model of the atom”.

## What was JJ Thomson’s atomic model?

J. J. In Thomson’s model, the atom is composed of electrons surrounded by a soup of positive charge to balance the electrons’ negative charges, like negatively charged “plums” surrounded by positively charged “pudding”.

What is Rutherford atomic model explain?

Rutherford’s atomic model is the model which described the atom as a tiny, dense, positively charged core called a nucleus, in which nearly all the mass is concentrated, around which the light, negative constituents, called electrons, circulate at some distance, much like planets revolving around the Sun.

### What are 2 differences between JJ Thomson’s model and Rutherford’s model?

Thomson model of atom and Rutherford model of atom are two models proposed by J.J. The main difference between Thomson and Rutherford model of atom is that Thomson model does not give details about the atomic nucleus whereas Rutherford model explains about the nucleus.

### What best describes Rutherfords model of an atom?

Rutherford’s model of the atom is also known as the planetary model because this is when he discovered the nucleus of the atom. He also discovered that the nucleus of the atom, located at the center of an atom, is only 1/3000th the size of the atom’s diameter. Also, surrounding the nucleus is an electron cloud.

What are defects of Rutherford’s atomic model?

RUTHERFORD S THEORY. There were two fundamental defects in Rutherford’s atomic model: According to classical electromagnetic theory, being a charge particle electron when accelerated must emit energy. We know that the motion of electron around the nucleus is an accelerated motion, therefore, it must radiate energy.

## What are the postulates of Rutherford’s atomic model?

An atom consists of a tiny positively charged nucleus at its centre.

• The positive charge of the nucleus is due to protons.
• The nucleus is surrounded by electrons that move around the nucleus with very high speed in circular paths called orbits.
• The number of electrons in an atom is equal to the number of protons in it.
• ## How did Rutherford’s model of the atom differ from Thomson’s?

The key difference between Thomson and Rutherford model of atom is that Thomson model of atom does not contain any details about nucleus whereas Rutherford model of atom explains about the nucleus of an atom.
