Answer:

✏✏✏✏✏✏

The model 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.

Answer 2

The model 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.

Features of Rutherford's Planetary model:

(1) It explained the existence of a nucleus.

(2) It explains the movement of electrons as a circulatory rotation of electron around the nucleus.

Defects:

(1) It cannot explain the stability of an atom.

(2) It cannot explain the number and velocity of electrons.

(3) according to this theory, the atomic spectrum is continuous and non linear but in fact it is linear and discontinuous.
