neils bohr's atomic model

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 ..

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 electro..

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..

. But when an electron jumps from a lower energy level to a higher one, some energy is absorbed while some energy is emitted. When an electron jumps from a higher energy level to a lower one, the amount of energy absorbed or emitted is given by the difference of energies associated with the two lev..

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 frequ..

Two new theories came to substantially modify Bohr's Atomic model. They a..

. He was awarded the Nobel Prize in 1908. The famous words of Rutherford on completing the alpha rays scattering experiment were: 'It was quite the most incredible event that has ever happened to me in life. It was almost as if you fired a 15 inch shell into a piece of tissue paper and it came back..
