explain Bohr's model of an atom.
Answers
Neils Bohr gave atomic model in 1913.The main points of this model are:
1) An atom consists of a central positive part called the nucleus which contains all the protons and neutrons.
2) Electrons which are present outside the nucleus revolve around the nucleus in definite circular paths called orbits or shells.
3) Each orbit has a fixed energy and the orbitals are represented by the symbols K, L,M, N etc or by the numbers 1,2,3 …
4) Each orbit can accommodate not more than a fixed number of electrons.
5) Electrons moving in the same orbit donot lose or gain energy.
6) Electrons lose energy on jumping from a higher orbit to lower one and vice-versa.
Answer:
Quantum mechanics, Quantum physics, the theory of relativity, etc are the modern subjects that interests, astound, and confuse almost everybody. These topics form the basis of modern physics. However, the very first-time quantum theory was incorporated in Bohr’s Model of an atom or Bohr atomic model. Later this model became the predecessor of complete quantum mechanical models.
Step-by-step explanation:
The physicist Niels Bohr said, “Anyone who is not shocked by quantum theory has not understood it.” He also said, “We must be clear that when it comes to atoms, language can only be used as in poetry.” So what exactly is this Bohr atomic model? Let us find out!
Bohr atomic model and the models after that explain the properties of atomic electrons on the basis of certain allowed possible values. The model explained how an atom absorb or emit radiation when electrons on subatomic level jump between the allowed and stationary states. German-born physicists James Franck and Gustav Hertz obtained the experimental evidence of the presence of these states.
