Answer 2

Answer:

Explanation:

Niels Bohr proposed the Bohr Model of the Atom in 1915.

The Bohr Model is a planetary model in which the negatively charged electrons orbit a small, positively charged nucleus similar to the planets orbiting the sun (except that the orbits are not planar).

                                                 or u can see this

According to Bohr’s theory:

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

ii. 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.

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

iv. 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.

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