Answer 2

According to Bohr’s theory:

⟶ The atom consists of a small positively charged nucleus at its centre.

⟶ The whole mass of the atom is concentrated at the nucleus and the volume of nucleus is smaller than the volume of the atom by a ratio of about 1:10.

⟶ The nucleus contains all the protons and neutrons of the atom.

⟶ The electrons of the atom revolve round the nucleus in definite circular paths known as orbits which are designated as K, L, M, N or numbered as n = 1,2,3,4 outward from the nucleus.

⟶ Each orbit is associated with a fixed amount of energy. Therefore, these orbits are also known as energy levels or energy shells.
