88. ​How does Schrödinger’s quantum mechanical model contradict Bohr’s model of hydrogen atom?

ANSWER:  

Bohr’s model of hydrogen atom states that an electron changes orbit only by absorbing or releasing energy. The electron is elevated to a higher-energy orbit when energy is absorbed and dropped to a lower-energy orbit when energy is released. However, according to Schrödinger’s quantum mechanical model, the precise paths of electrons cannot be determined accurately as required by Bohr’s model. Schrödinger’s model states that the location and energy of electrons around a nucleus can be specified using three terms: shell, subshell, and orbital.​
