Bohr's Model of an Atom
Rutherford's model had a major drawback. It could not explain why ultimately electrons did not fall into the nucleus by taking a spiral path. This was in concurrence with the electromagnetic theory that states 'if a charged particle undergoes accelerated motion then it must radiate energy (lose) co..

In order to explain the stability of an atom Neils Bohr in 1913 proposed a new theory to explain the arrangement of electrons in an atom. According to Neils Bohr, the electrons could revolve around the nucleus only in 'certain orbits' (en..
Bohr's Theory of Hydrogen Atom
Niels Bohr suggested that the problem about hydrogen spectrum can be solved if we can make some assumptions. According to classical theory, the frequency of the electromagnetic waves emitted by a revolving electron is equal to the frequency of revolution. As the electrons radiate energy, ..

Bohr's atomic model explained successfully:
The stability of an atom. Bohr postulated that as long an electron remains in a particular orbit it does not emit radiation i.e. lose energy. Hence it does not become unstable. The atomic spectrum of hydrogen was explained due to the concept of definite energy lev..
Arrangement of Electrons in an Atom (Bohr-Bury Scheme)
Electrons revolve around the nucleus in different energy levels or shells and each shell is associated with definite energy. The energy of the K shell is the least while those of L, M, N and O shells increases progressively. We also know that any system that has least energy is the most stable. 1 s..

Great tutor! Was both helpful and responsive to questions! Did not just want to give me an answer, but took the time to explain any steps I did not understand! - Robert
They made my daughter to quiz herself with flashcards. The strategies that taught,helped her to learn the mulitiplication facts more easily- Slavic
Really good tutors. Real helpful and made things easy to understand. Tutor vista is a real online tutoring company
It has tought me how to make my word more explained and This has tought me alot that i need to know , I am thankful -- Mark
