Question

Which of the following describes the Bohr atomic model?

A. Protons, neutrons, and electrons orbit around each other in set paths.
B. The nucleus contains protons and neutrons and is orbited by electrons.
C. Protons, neutrons, and electrons occupy the same spaces within the atom.
D. Protons occupy the center of an atom, with neutrons and electrons circling.

Answer 1

Answer: option B. The nucleus contains protons and neutrons and is orbited by electrons.

This is the planetary model, which is so known nowadays, but it is not correct. The quantum model is based in orbitals (not orbits), which are regions around the nucleus where are the electrons, but they are not circling around the nucleus.
