Goldstien performed discharge tube experiments in which he used perforated cathode and gas at a very low pressure after passing high current between the electrodes it was found that some rays were coming from the sides of cathode, which passed through the holes in anode and produce a green flouresense on the opposite sides wall coated with zinc sulphide.These rays were called as anode rays.They were contaning positive charge.Goldstien named them protons.

something to do with protons and stuff.
Nucleus: ernest Rutherford neutron: James chadwick protons: ernest Rutherford electron: democritus atom: john Dalton
Physics has not managed to discover a particle that accounts for mass
Rutherford discovered that almost entire mass of an atom is located in the nucleus, and then, the neutron was discovered by Chadwick.
put it in your mind! The Atomic number. is number of protons, While The Mass number. is number of protons and electrons. when you subtract both get the number of electrons and this for any element but not all elements have same atomic numbers or mass and Rutherford First discover "transmutation" from element to other element which determine by their atomic and mass numbers.
Rutherford shot beta particles at gold foil to discover protons, but i have never heard of an aluminum foil experiment.
Sir J.J Thomson first discovered that atoms had a negatively charged particle called an "ELECTRON". Afterwards , Goldstein discovered "PROTONS", the positively charged particles.
Rutherford's gold foil experiment did not discover the existence of any subatomic particles, but it did show the existence of a small, tightly packed, positively charged nucleus and thus led to the discovery of protons.
The atomic number of an atom is the number of protons in the nucleus of that atom. The number of electrons will equal the number of protons in that atom if that atom is a neutral one. Other than that, we would have to know the atomic number (which is the number of protons that atom has), and the overall charge of the atom. With that information, we could discover how many electrons that atom had by simple mathematics. If an atom had 11 protons and a charge of +1, it would have one less electron than the number of protons, or 10 electrons. If an atom had 53 protons and a charge of -1, it would have 54 electrons. The ratio from atomic number to the number of protons in an atom is 1:1. The elements are categorized by the number of protons they have, as that is the difference between two elements. Conceptually, atomic number and proton number are the same.
When an accelerator in which protons are raised to electron-volts.
It would have taken scientists longer to discover protons. A+
