WebDalton’s model portrays atoms as solid spheres. All atoms of the same element do not have the same mass Atoms of the same element do have different masses sometimes because there are different isotopes. An isotope is an element that has a different number of neutrons, but the same number of protons and electrons. WebThomson placed two oppositely-charged electric plates around the cathode ray. The cathode ray was deflected away from the negatively-charged electric plate and towards …
