Question

write bohr's postulates and draw two shells of atom?​

Answer 1

Answer:

Main postulates of Bohr's atomic model

1) The electrons revolving around the nucleus are confined to certain fixed orbits called shells or energy levels, each of which is associated with a fixed amount of energy.

2) While it is revolving around the nucleus in an orbit, an electron neither loses nor gains energy.

3) An electron revolving in a particular orbit, on gaining a certain amount of energy, jumps to the next orbit or vice versa. Si ce each orbit is associated with a fixed amount of energy, Bohr called it energy level...
