The best analogy that suggests that electrons moves round the nucleus in an atom is the Bohr model.
According to Neil Bohr;

- These electrons are in spherical orbits called shells or energy levels around the nucleus.
- The nucleus is the tiny massive center of the atom.
- Electrons can undergo transitions from one level to another.
