WebWhich statement is true of the quantum mechanical model, but not of the Bohr model? a. Electrons orbit the nucleus in simple circular orbits, just like planets orbit the Sun. b. The exact path that an electron follows within an atom cannot be specified. c. The electron is attracted to the nucleus of the atom. WebBohr's model had one significant drawback - they were only a 2-D diagram of the truth. In reality the actual model of the atom is the Sommerfield atom, where we see electrons travelling in an elliptical path around the nucleus, but in the xyz plane. In plain words, Bohr's model was a 2-D shape while Sommerfield's was a 3-D shape of an atom. Share

They cover the concept of using a model in science and how a Bohr Diagram is a representation of an atom. Then they introduce the Bohr model, explain WebPostulates of Bohr Atomic Model. Electrons revolve around the nucleus in a fixed circular path termed “orbits” or “shells” or “energy level.”. The orbits are termed as “stationary … WebIn the quantum mechanical version of the Bohr atomic model, each of the allowed electron orbits is assigned a quantum number n that runs from 1 (for the orbit closest to the nucleus) to infinity (for orbits very far from the nucleus). All of the orbitals that have the same value of n make up a shell. how to spray paint a mirror
