Atomic Structure
According to Bohr's atomic model, electrons revolve around the nucleus in stationary orbits.
Explain Bohr-Bury scheme.
Bohr-Bury scheme-
i. The maximum number of electrons that could be present in a shell is given by the rule $$2n^2$$, where n is the orbit number or energy level.
Example, in first shell, $$n = 1,$$ then number of electrons = $$(2\times (1)^2) = 2 \ electrons$$
Similarly, for other shells, the diagram is shown below:
ii. The maximum number of electrons that can be accommodated in the outermost orbit is 8.
iii. Electrons are not accommodated in a given shell unless all the inner shells are completely filled.
According to Bohr's atomic model, electrons revolve around the nucleus in stationary orbits.
Bohr proposed his atomic model based on :
The approximate radius of a $$H-atom$$ is $$0.05\ nm$$, and that of a proton is $$1.5\times 10^{-15}m$$. Assuming both the hydrogen atom and the proton to be spherical, calculate a fraction of the space in an atom of hydrogen that is occupied by the nucleus.
Atomic models have been improved over the years. Arrange the following atomic models in the order of their chronological order. (i) Rutherfords atomic model (ii) Thomsons atomic model (iii) Bohr's atomic model
