Chemistry question??

empiracal formula is a way of writing chemical coupounds that showws how many of each type of ataom there are in 1 molecule (H2O, water @ hydrogen and 1 oxygen) and in rutherfords gold foil experiment, rutherford aimed a beam of positively charged particals, given off of a radioactive substance, at gold foil and he measure the angles of deflection. most went straight through, however some were reflected back at angles that seemed to defy logic. so he reasoned that there must be a positively charged center of an atom and it must be very tiny in proportion to the rest of the atom. In short he dicovered the atomic nucleus.
