Answer 1

Answer:

Ernest Rutherford is known for his pioneering studies of radioactivity and the atom. He discovered that there are two types of radiation, alpha and beta particles, coming from uranium. He found that the atom consists mostly of empty space, with its mass concentrated in a central positively charged nucleus.Rutherford's experiment showed that atoms consisted of a dense mass which was surrounded by mostly empty space - the nucleus! ... The conclusion that could be formed from this result was that atoms had an inner core which contained most of the mass of an atom and was positively charged.Rutherford's model was unable to explain the stability of an atom. According to Rutherford's postulate, electrons revolve at a very high speed around a nucleus of an atom in a fixed orbit. ... Rutherford's theory was incomplete because it did not mention anything about the arrangement of electrons in the orbit.Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. Based on these results, Rutherford proposed the nuclear model of the atom.
