Answer to Question #141121 in Inorganic Chemistry for Sarita bartwal

Question

a) Predict the shape of brf4^-1 using caper theory.
b) write the postulates of bohr's atomic theory

Answer 1

The Bohr model postulates that electrons orbit the nucleus at fixed energy levels. Orbits further from the nucleus exist at higher energy levels. When electrons return to a lower energy level, they emit energy in the form of light.

An electron can revolve around the nucleus in certain fixed orbits of definite energy without emission of any radiant energy. Such orbits are called stationary orbits.2)Only those orbits are allowed for which the angular momentum of the electron is an integral multiple of 2π/nh​Thus,L=2π/nh
