What was rutherfords model?

Rutherford came up with a nuclear model he proposed that instead of a field of a positive charge there was some sort of compact nucleus which contained all of the positive charges of the atom and he thought the negative charge existed in a sort of cloud around this central nucleus. but there some doubts on rutherfords model there didn't seem to be anything stopping this cloud of negative charge rushing in towards the positive nucleus meaning the atom should just automatically collapse wich we know it doesnt.
