Here is a good link for neutrons. Experimental data came in about 1932 from scattering experiments in which Be metal was bombarded with alpha particles.

You can get dates for the other discoveries by Googling "discovery proton" or "discovery electron".

Do you have questions on how to calculate each at the end?

Two actually, for the "Data Supporting Discovery,"when it says data, does it mean I have to include a brief explanation about the experiment from the previous group?

And for the calculations, is that the "official" way to calculate them, or is there another way?

I think for the first, yes. Just a short summary of the work.

For the second I would make the following observations: The question isn't clear as to WHAT you are to calculate. Is it the number of p, n, e, or the charge, or the mass or just what. I assume it is the number of p, n, e.
1. proton. The number of protons in an element is the atomic number.
2. The number of neutrons is the mass number minus the atomic number. Note that mass number is the number protons + number of neutrons (both are whole numbers) while the atomic mass is seldom a whole number and is the average atomic mass of all of the natural isotopes of that element relative to carbon 12 set at 12.0000.
3. The number of electrons in an element is the same as the number of protons in that element; i.e., the number of electrons = atomic number = number of protons.

To fill in the chart, you need to match the subatomic particle found, scientist, experiment, and data supporting discovery.

1. Proton is matched with Rutherford, the Gold Foil Experiment, and the data supporting discovery is the deflection of alpha particles by the gold foil.
2. Neutron is matched with Chadwick, but you are missing the experiment and data supporting discovery. One experiment that led to the discovery of the neutron is the bombardment of beryllium with alpha particles. Data supporting discovery includes the observation of neutral radiation and the determination of neutron mass and charge.
3. Electron is matched with Thomson, the Cathode Ray Tube Experiment, and the data supporting discovery is the deflection of the cathode ray by electric and magnetic fields.

To calculate each:

1. Atomic Number: The atomic number represents the number of protons in an atom. It can usually be found on the periodic table for each element. Simply identify the element you are interested in and read its atomic number value.

2. Atomic Mass-Atomic Number: To calculate the atomic mass of an atom, subtract the atomic number (number of protons) from the atomic mass number (which is the sum of protons and neutrons in the nucleus). For example, if an atom has an atomic mass of 20 and an atomic number of 8, then the number of neutrons would be 20 - 8 = 12.

3. Atomic Number-Charge: It appears you are referring to the calculation of the number of neutrons in an atom, assuming you already know the atomic number and charge. To calculate this, subtract the atomic number (number of protons) from the sum of the atomic number and the charge. For example, if an atom has an atomic number of 8 and a charge of +2, then the number of neutrons would be (8 + 2) - 8 = 2.
