Atoms are made up of protons, neutrons, and electrons. However, if you remove any of these particles the atom will have different properties. An atom is the smallest particle of an element that has all the properties of the element. For example, sodium in its pure form reacts violently with water.

WebApr 8, 2024 · Hence, the proton was discovered by Goldstein accidentally. The same experiment was then conducted on anodes resulting in the flow of another ray. This time, the particles had a significant mass but traveled straight when there was no electrical or magnetic field around.
Atomic number In chemistry, the number of protons in the nucleus of an atom is known as the atomic number, which determines the chemical element to which the atom belongs. For example, the atomic number of chlorine is 17; this means that each chlorine atom has 17 protons and that all atoms with 17 … See more A proton is a stable subatomic particle, symbol p , H , or H with a positive electric charge of +1 e (elementary charge). Its mass is slightly less than that of a neutron and 1,836 times the mass of an electron (the See more The concept of a hydrogen-like particle as a constituent of other atoms was developed over a long period.
