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 negatively - charged electrons. Rutherford used alpha particles (positively - charged) in his gold - foil experiment. So, they both used charged particles. Thomson did not use emission spectra to discover electron clouds, and Rutherford's model was not an indivisible sphere. Also, Rutherford did not discover electron clouds.

Answer:

They both used charged particles in their experiments.
