Calculate velocity of electron in bohr first orbit of hydrogen atom
Entropy (S) is a molecular 'disorder', or more precisely 'the number of microscopic arrangements of energy possible in a macroscopic sample'. Entropy depends strongly on the state
The energy of an electron in the first Bohr orbit of H atom is-13.6eV . The possible energy value(s) of the excited state(s) for electrons in Bohr orbits to hydrogen is(are):
