Bohr turned to Planck’s quantum theory to explain the stability of most atoms. He found that the ratio of energy in electrons and the frequency of their orbits around the nucleus was equal to Planck’s constant (the proportion of light’s energy to its wave frequency, or approximately 6.626 x 10-23 ).
