The theory notes that electrons in atoms travel around a central nucleus in circular orbits and can only orbit stably at a distinct set of distance...

Bohr was the first to discover that electrons move around the nucleus in different orbits and that an element’s properties are determined by the nu...

The nucleus in the atom’s Bohr model holds most of the atom’s mass in its protons and neutrons. The negatively charged electrons, which contribute...

Many modifications have been introduced to the Bohr model, most notably the Sommerfeld model or Bohr – Sommerfeld model, which suggested that elect...

J. J. Thomson in 1897 discovered Electron when he was studying the properties of the cathode ray.
