Question

list out the postulates of Thomson's model of an atom and Bohr's model of an atom ​

Answer 1

Answer:

Model, History, Limitations ...

According to the postulates of Thomson's atomic model, an atom resembles a sphere of positive charge with electrons (negatively charged particles) present inside the sphere. The positive and negative charge is equal in magnitude and therefore an atom has no charge as a whole and is electrically neutral.

Answer 2

Explanation:

Thomson

Rutherford Neils Bohr

An atom consists of a

sphere of positive charge

with negative charged

electrons embedded in it.

There is a positively

charged, dense center in an atom called the nucleus. Nearly the whole mass of an atom resides in the nucleus. Only certain special orbits known as discrete orbits of electrons are allowed inside an atom.

The positive and the

negative charges in an atom are equal in magnitude due to which an atom as a whole is electrically neutral. The electrons revolve around the nucleus in a circular path. While revolving in discrete orbits the electrons do not radiate energy.

The size of the nucleus is very small as compared to the size of an atom.
