Why could Borhr's model be called a planetary model pf the atom?

Answer 1

Bohr's model can be referred to as a planetary model of the atom because it depicts electrons orbiting the nucleus in defined paths, similar to how planets orbit the sun. In this model, electrons occupy specific energy levels or orbits, analogous to the fixed orbits of planets. This visualization emphasizes the structured and quantized nature of electron behavior, aligning with classical mechanics, despite its limitations in accurately describing more complex atomic behaviors.
