Which of the following viewed the atom as having a nucleus made up of protons and neutrons, with electrons orbiting the nucleus in fixed, stable orbits, much like the planets orbit the sun?

The correct answer is C. Bohr's model

Explanation:

Bohr's model of the atom developed in 1913 proposed each atom contained a nucleus with protons and neutrons. Also, there were electrons that orbited the nucleus. About this, Niels Bohr proposed the orbits of electrons were similar to those of planets around the sun; however, these did not occur due to gravity but to attraction forces. This model integrated new accurate ideas about the atom. However, this model was still inaccurate because particles in an atom are electrically charged and electrons do not orbit in fixed stable orbits and cannot be compared to the movement of planets around a star.
