Question

state two postulates of Bohr's model of atom what is the maximum number of electrons that can be accommodated in a shell? Write the electronic configuration of chlorine atom atomic number of chlorine is 17​

Answer 1

Answer:

The two postulates of bhors model are

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.

Bohr's 2nd postulate tells us that electrons orbit the nucleus only in those orbits for which the angular momentum is an integral multiple of nh/2(pi).

e.c of chlorine = 2,8,7

Answer 2

Explanation:

hey here is the answer

Postulates of Bohr's Model of an atom: ... In an atom, electrons(negatively charged) revolve around the positively charged nucleus in a definite circular path called as orbits or shells. 2. Each orbit or shell has a fixed enery and these circular orbits are known as orbital shells.

Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.

Chlorine atom (Cl) has elctronic configuration of 2,8,7 . Its valency is 1- (The atomic number of Chlorine is 17. Since Chlorine has 7 electrons in its valence shell it would take much less energy to acquire an electron an reach the stable 8 electrons in a shell configuration rather than loosing its 7 electrons.
