Rutherford Gold Foil Experiment involved shooting alpha particles ( golden foil. Most of the alpha particles moved through the foil. On occasion an alha particles would bounve back after impacting the foil What do both observation mean with regard to the overall essentially helium nuclei at of atom? Why most of alpha particles passed through the foil? Why Some of the alpha particles bounced back from the foil? Q2. Sketch an electromagnetic wave and label the wavelength and an amplitude and which part of the electromagnetic wave provides information about the number of photons? INSRT STD Solution Rutherford experiment overall shows that atom has its most of space empty. And only central part of atom has mass confined of atom in form of nucleus. A. Electrons revolve around nucleus in an atom. The space between the orbitals is empty and that\'s why most of alpha particles passed through the coli. Because they passed through the empty space within the orbitals. B. Some alpha particles were bounced back because they collide with the nucleus which is present in the middle of atom. The mass of atom is in the nucleus so the alpha particles collided and were bounced back. .
