WebBohr Model : Rutherford Model : Description: It is an atomic model that explains the movement of electrons in the energy levels or orbit located around the nucleus. It is atom theory that states that an atom contains a central core where the entire mass is concentrated. Lightweight particles usually move around the core. WebMay 15, 2024 · Bohr’s model was proposed by Niels Bohr and Ernest Rutherford in 1913. That they consist based on their nuclei containing protons and neutrons is then surrounded by electrons rotating in their orbit (a certain energy level). Orbits are also known as atomic shells. Advantages of Bohr Theory
WebBohr modified Rutherford’s basic model by proposing that electrons had set energy levels (Fig. 7). This is the model of the atom most commonly portrayed in textbooks: a nucleus orbited by electrons at different levels. It helped solve the problem of the collapsing atom and earned Bohr a Nobel Prize.
