1. Who discovered Proton?Ernest Rutherford in 1917
2. How heavy is Proton?Approximately 1.6726 x 10^-27 kg
3. What is the classification?A baryon composed of two up quarks and one down quark
4. What is the atomic number (z)?The number of protons in an atom's nucleus, defining the element
5. Why does a proton have a positive charge?A proton is made of two up quarks and one down quark. The quarks give the proton a net charge of +1. This positive charge is what makes the proton special.
6. How many protons are in a hydrogen atom?A hydrogen atom has one proton in its nucleus. That single proton makes hydrogen the simplest element. It is called protium.

Baryon: A composite subatomic particle made of three quarks.
Strong Nuclear Force: The fundamental force that binds quarks and nucleons together.
Nucleosynthesis: The process by which new atomic nuclei are created from pre-existing nucleons and isotopes.
