Question

Rutherford model of an atom​

Answer 1

The Rutherford model, also known as planetary model is a model which tried to describe an atomdevised by Ernest Rutherford. Rutherford directed the famous Geiger–Marsden experiment in 1909 which suggested, upon Rutherford's 1911 analysis, that J. J. Thomson's plum pudding model of the atom was incorrect. Rutherford's new model[1] for the atom, based on the experimental results, contained new features of a relatively high central charge concentrated into a very small volume in comparison to the rest of the atom and with this central volume also containing the bulk of the atomic mass of the atom. This region would be known as the "nucleus" of the atom.

Answer 2

Rutherford's model of an atom



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 is concentrated in the nucleus .

2.The nucleus is surrounded by negatively charged electron. The electrons are revolving around the nucleus in circular path at very high speeds .The circular path 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 atom is empty space .
