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 atom (i.e., 10 - 1 0 m). (ii..

Atomic to Astronomical Range of Variation of Length
Some objects have a wide range of lengths in the universe. They are tabulated below in the order of magnitude of their lengths. Size/distance of the object Order of magnitude of length (m) Radius of nucleus 10 -14 Diameter of an atom 10 -10 Radius ..

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 levels. The o..
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 energ..
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 ..

The wave character of an electron and uncertainty in its position and momentum gave a serious blow to Bohr's model of an atom. According to Bohr, the electrons revolve around the nucleus in certain well-defined circular orbits. But the idea of uncertainty in position and velocit..
Trends in the Modern Periodic Table
The distance from the centre of the nucleus to the outermost shell of an atom is called the atomic radius of that atom..

This is a great help for my son, who is getting help with all major subjects like math, science and English...
I am Jessica from New York, I got excellent English tutors from Tutor Vista, who helped me lot to overcome my grammar mistakes, Thanks a lot...
I asked a Math question in the chat box in tutorvista. I was amazed to see live response from the tutor who helped me with my questions. That was great. I joined their online regular tutoring so that I can get such help anytime. - Mary
I am a big fan of TutorVista tutoring. I am studying here from couple of months now and I want to continue for ever. - Ben
