Answer:
Bohr's model of the hydrogen atom is based on three postulates: (1) an electron moves around the nucleus in a circular orbit, (2) an electron's angular momentum in the orbit is quantized, and (3) the change in an electron's energy as it makes a quantum jump from one orbit to another is always accompanied by the ...

Answer:
(1) Electrons revolve around the uncleus in certain , definite circular paths , called orbits . They are also known as energy levels or shells .
(2) Each orbit is associated with a definite amount of energy . Hence these orbits are called energy orbits or energy levels or energy shells .
(3) As the value of n increases , the size and energy of the orbit increases .
