WebAug 12, 2014 · 1 Answer. Daniel W. Aug 12, 2014. Rutherford described the atom as consisting of a tiny positive mass surrounded by a cloud of negative electrons. Bohr thought that electrons orbited the nucleus in quantised orbits. Bohr built upon Rutherford's model of the atom. In Rutherford's model most of the atom's mass is concentrated into the … WebThe electrons are distributed around the nucleus and occupy most of the volume of the atom. The Bohr model of the atom proposed by Neils Bohr is similar to the planetary motion. Hence this model is also known as the planetary model of the atom. He describes that the negatively charged electrons will orbit around the positively charged nucleus.

WebWho is the father of planetary model? Bohr was also a philosopher and a promoter of scientific research. Bohr developed the Bohr model of the atom, in which he proposed that energy levels of electrons are discrete and that the electrons revolve in stable orbits around the atomic nucleus but can jump from one energy level (or orbit) to another. WebAccording to the Bohr model, often referred to as a planetary model, the electrons encircle the nucleus of the atom in specific allowable paths called orbits. When the electron is in one of these orbits, its energy is fixed. The ground state of the hydrogen atom, where its energy is lowest, is when the electron is in the orbit that is closest ...

WebThe Bohr model was also the first atomic model to incorporate quantum theory, meaning that it’s the predecessor of today’s more accurate quantum-mechanical models.
