Mr. soto was trying to explain how electrons move around the nucleus of an atom in circular orbits. which analogy best represents this concept?
a) earth spins on its axis.
b) the planets go around the sun.
eliminate
c) particles of dust move around in random order.
d) a ball starts moving when another ball hits it.

The analogy that best describes is "The planets go around the sun."

Explanation:

The best analogy that suggests that electrons moves round the nucleus in an atom is the Bohr model.  According to Neil Bohr, Based on Rutherford's model, he suggested that the extra nuclear part consists of electrons. These electrons are in the spherical orbits called shells or energy levels around the nucleus. The nucleus is the tiny massive center of the atom. Transition of electrons takes place from one level to another.
