The Bohr model explains why hydrogen has fixed energy levels and emits light at specific wavelengths. Here is the formula, with a worked example.

Have you ever wondered why the nucleus of an atom stays together when it contains positively charged protons that naturally repel one another? Or why nuclear power plants can release enormous amounts of energy from such tiny amounts of fuel? The answer lies in a fundamental concept in nuclear physics: nuclear binding energy. Nuclear binding…
