Bohr nuclear atom

WebThe early 20th century brought a succession of scientific models, or theories, to describe the atom and its components. As experiments revealed more about subatomic particles, atomic models evolved from Thomson’s “plum pudding model,” to Rutherford’s nuclear model, then to Niels Bohr’s planetary model, and eventually to the currently-accepted quantum … 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.
