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..

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..

Rutherford's Atom Model (Main Features) - (i) Every atom consists of a nucleus containing the entire +ve charge. The whole mass of atom is concentrated at this core. (ii) The size of the nucleus i.e., 10 - 1 5 m is very small compared to the size of the ..

This was a wonderful session. Tutor was able to see my hesitation and doubt..He took the time to go over the basics with me and explained it in a way that my instructor never explained-so now I can work easier! Thank you Tutor Vista!
I dont even think my school teachers has as much knowledge as this tutors does. Tutor Vista ROCKS.........
Tutor is well courteous and patient. I look forward to working with the same tutor if possible.
Really patient and addressed me in a great tone, I was really confident on the topic now. Thanks!!!
