Question

Describe Rutherford's model of an atom.

Answer 1

On the basis of Alpha particle scattering experiment, Rutherford gave a nuclear model of the atom.
Rutherford's model of atom can be described as follows:

1. An atom consists of a positively charged, dense and very small nucleus containing all the protons and neutrons . Almost the entire mass of an atom lies in the nucleus.

2. The nucleus is surrounded by negatively charged electrons. The electrons are revolving around the nucleus in circular paths at very high speeds. The circular paths of the electrons are called orbits.

3. The electrostatic attraction between the positively charged nucleus and negatively charged electrons holds the atom together.

4. An atom is electrically neutral. This is because the number of protons and electrons in an atom is equal.

5.Most of the atoms is empty space.

Answer 2

Hey mate,

◆ Rutherford's model of atom -

• In 1911, Rutherford coined the planetary model of atom with the help of his gold-foil experiment.
• In this model, he bombarded alpha particles from radioactive elements on the shining screen.
• He compared the results to atomic structure demonstrating that atom has heavily charged nucleus surrounded by empty space.

From the gold-foil experiment Rutherford concluded that -

• Most of the atom is empty space containing negative charges.
• Atom have very small positively charged nucleus.

Hope this helps...
