Question

Electrons revolve around the _____ in well defined orbits.

Answer 1

According to Bohr's atomic model of an atom:

• Atom consists of a positively charged nucleus present in the center of the atom around which electrons revolve in discrete orbits which are associated with a certain fixed amount of energy.
• These orbits are also known as energy shells or energy levels.

Therefore, Electrons revolve around the nucleus in well-defined orbits.
