Bohr Atomic Model
Q1: What is a Bohr model of an atom?
Answer:
The model of the atom proposed by famous scientist Neil Bohr in 1915 was came to be known as the Bohr model of an atom. This model was the modification of Rutherford’s model of an atom and states that electron revolves around the nucleus in fixed orbits without losing any energy.
Q2: What are the postulates of Bohr’s model of an atom?
Answer:
Major postulates of Bohr’s model of the atom are,
- Electrons revolve around the nucleus in the fixed circular orbits called the shells.
- Electrons do not lose energy when they revolve in these circular orbits(shells)
- They only lose or gain energy if they jump from one orbit to another orbits.
- Each orbit has energy associated to it.
Q3: What are the limitations of Bohr Atomic Model Theory?
Answer:
Various limitations of the Bohr Atomic Model are it fails to explain the Zeeman Effect and Stark Effect. It also does not approve the already proven Heisenberg’s Uncertainty Principle.
Q4: What does Bohr’s atomic model explain?
Answer:
Bhor’s model explain the energy radiated by the electrons as according to him the electron revolve around the positive charge(nucleus) in a fixed orbit and their energy remains constant. They only radiate energy when they jump from one energy orbit to other energy orbit.
Q5: Who was the first to discover electrons?
Answer:
Electrons were first discovered by the famous scientist J. J. Thomson while he was studying the properties of the cathode ray.
Bohr’s Model of an Atom
Bohr’s Model is an atomic model proposed by Danish Physicist Niels Bohr in 1913. According to this model, in an atom, the electrons revolve around the nucleus in definite energy levels called orbits/shells. This model provides a basic understanding of the concept of the atom and its constituents.
