Answer:

Thompson Model Rutherford Model Bohr Model

In this model, an atom consists of a positively charged sphere and the electrons embedded in it. The number of electrons is equal to the number of protons so the atom is electrically neutral. In this model, there is a positively charged centre in an atom called the nucleus. Nearly all the mass of an atom resides in the nucleus. The electrons revolve around the nucleus in circular paths. The size of the nucleus is very small as compared to the size of the atom.

In this model, only certain special orbits known as the discrete orbit of electrons, are allowed inside the atom. While revolving the electrons do not radiate energy. These orbits are called energy levels or shells.

Answer:

The models of atom are=

1) Rutherford model of an atom.

An atom is mostly empty space,with electrons orbiting a punitively charged nucleus.

2) Bohr model of atom.

An atom consist of elecrtons which revolve in fixed orbits and in gixed no. around the nucleus of atom.

3) JJ Thomson's model of an atom.

He described atom as an plum pudding which comprise of protons and electrons.
