Question

what did thomsons and rutherfords experiments have in common? they both used charged particles in their experiments. they both used emission spectra to discover electron clouds. they both compared the atom to an indivisible sphere. they both discovered electron clouds.

Explanation:

Thomson used cathode - ray tubes with electrons (charged particles) in his experiment to discover electrons. Rutherford used alpha - particles (positively charged) in his gold - foil experiment. Emission spectra were not common in both, Rutherford disproved the indivisible sphere model, and electron clouds were not a common discovery.

Answer:

They both used charged particles in their experiments.
