According to the planetary model, the speed of an electron revolving around the nucleus is given as follows;
v = e/√4∈₀mr.
The orbital speed of an electron, orbiting around a nucleus in a circular orbit of radius 50 consistent with the Bohr model, regularly called a planetary version, the electrons encircle the nucleus of the atom in precise allowable paths referred to as orbits. whilst the electron is in one of these orbits, its energy is fixed.
The ground nation of the hydrogen atom, wherein its electricity is lowest, is whilst the electron is inside the orbit that is closest to the nucleus. The orbits which can be similar to the nucleus are all of the successively extra power. The electron isn't allowed to occupy any of the areas in between the orbits. A regular analogy to the Bohr version is the rungs of a ladder pa is 2. 2×106ms−1.
