Question

Energy of the electron in H-tom is ground state is 13.6 eV. What is the energy in first excited state? 1) 1.2 eV 2) 1.5 eV 3) 2.1eV 4) 3.4eV​

Answer 1

Explanation:

$This is about 7 quadrillion revolutions per second or equivalently 7 thousand trillion revolutions per second. This is fantastically fast but it is much slower than the rate of rotation of nuclei. At this rate of revolution all that can be observed of the electron in its orbit is its dynamic appearance.$
