Question

• What do you mean by Bohr's stable orbit ?​

Answer 1

Answer:

In 1913 Bohr proposed his quantized shell model of the atom (see Bohr atomic model) to explain how electrons can have stable orbits around the nucleus. The atom will be completely stable in the state with the smallest orbit, since there is no orbit of lower energy into which the electron can jump.

Answer 2

Bohr's stable orbits are explained below:

• Bohr improved rutherford's model of an atom and provide some postulates that explain the stability of the atom.
• Rutherford's model has limitations as he could not explain the stability of the atom because according to him electrons move continuously and if it is so then it would undergo acceleration and finally fall into the nucleus.
• Bohr's orbits are stable as the electrons in these atoms move in a specified circular orbit which is also known as shells.
• These orbits are stable because the energy of each orbit is fixed.
• The energy of each orbit is an integral multiple of the shell in which electric. is present. The energy of the lowest level or ground level is lowest while it increases with an increase in shell number.
• Electrons need to gain energy to reach the highest orbit to equalize with the energy of higher orbits.
