Answer 1

$\huge\purple{\mathbb{AnsWer:}}$

Based on the results of the α-particle scattering experiments, Rutherford put forth his atomic model. An atom contains a positively charged centre called the nucleus of the atom. Almost all the mass of the atom is concentrated in the nucleus.

The electrons of the atom revolve around the nucleus in fixed, circular orbits. The size of the nucleus is many times smaller than the size of the atom. The nucleus of an atom is 10,000 times smaller than the atom.

Drawbacks of Rutherford’s Model of an Atom

• Rutherford’s atomic model could not explain how moving electrons could remain in their orbits.

• Any charged particle during acceleration would radiate energy, and while revolving, it would lose its energy and eventually fall into the nucleus.

• This means that the atom would be highly unstable.

• But, matter is composed of stable atoms.

• Thus, the major drawback of Rutherford’s atomic model was that it could not explain the stability of atoms.

Rutherford’s Model of an atom is similar to that of the Solar system. Just as in the solar system, the Sun is at the centre and the planets revolve around it, in an atom, the electrons revolve around the centrally located nucleus containing protons.
