Question

Why Rutherford's atom model is called solar model?

Answer 1

the electrons move around the massive nucleus like planets orbiting the sun. That's why his model is called the planetary model. Rutherford didn't know exactly where or how electrons orbit the nucleus.

Explanation:

Rutherford model, also called Rutherford atomic model, nuclear atom, or planetary model of the atom, description of the structure of atoms proposed (1911) by the New Zealand-born physicist Ernest Rutherford.Rutherford atomic modelPhysicist Ernest Rutherford envisioned the atom as a miniature solar system, with electrons orbiting around a massive nucleus, and as mostly empty space, with the nucleus occupying only a very small part of the atom.
