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 ..

In 1913, Neils Bohr proposed a model of an atom based on the Planck's quantum theory of radiation. The basic postulates of Bohr's theory are: * An atom consists of a small, heavily positively charged nucleus around which electrons revolve in definite circula..

where 'Z' is the nuclear charge, which is equal to atomic number. Although Bohr's model successfully explained the stability and the line spectrum of hydrogen, it had its limitations. They wer..

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' (energy levels), each orbit having a differ..

Niels Bohr suggested that the problem about hydrogen spectrum can be solved if we can make some assumption..

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..

Maximum number of electrons that can be accommodated in a shell is given by 2n 2 where n=shell number For 1 s t energy level, n = 1 Maximum number of electrons in 1 s t energy level = 2n 2 2 x (1) 2 = 2 For 2 n d energy level n=2 Maximum number of electrons in the 2 n d energy le..
