Question

multiple-choice question select the correct description of bohrs \planetary model\ a solid sphere with no particles inside electrons orbiting on energy levels around the nucleus electrons randomly scattered around a nucleus rewatch next question

Explanation:

Bohr's Planetary Model (also known as the Bohr model of the atom) proposes that electrons move in specific, circular orbits (energy levels) around the nucleus of an atom. The first option describes a solid sphere with no particles inside, which is incorrect (the atom has a nucleus and electrons). The third option describes electrons randomly scattered, which is more like the Thomson or Rutherford - before - Bohr models (e.g., Rutherford's model had electrons as "scattered" around the nucleus, but Bohr introduced the idea of fixed energy levels). The second option correctly states that electrons orbit on energy levels around the nucleus.

Answer:

B. electrons orbiting on energy levels around the nucleus
