8 Facts about Atomic Theory
Let me show you the interesting Facts about Atomic Theory by reading the explanation below. Atom is the smallest particle in an element. There are three parts which compose an atom. They are neutrons, protons and electrons. Atom is considered as the basic building block in a matter. The positive electrical charge is seen proton. The electrons have the negative electrical change. The neutral zone is seen in neutrons. Here are other facts about atomic theory:
Facts about Atomic Theory 1: proton and electron
Proton and electron are attracted each other electrically. Even though both have opposite in sign, both are equal in magnitude.
Facts about Atomic Theory 2: neutron
As I have stated before, neutron has neutral electrical charge. It means that the proton or even electron will never be attracted to neutron electrically for it does not have any charge.

Facts about Atomic Theory 3: the size
The size of neutron and proton is a bit similar. But both are larger than electron. Moreover, the mass of neutron and proton are similar. But the mass of electron is smaller if you compare it with proton. It is 1840 times smaller than proton’s mass.
Facts about Atomic Theory 4: the smallest unit of matter
As I have stated before, atom is smallest unit of a matter. It can be found inside the gas, plasma, liquid or even solid matter. It is not easy to see the atom for it has a very tiny size. If you study about atom, you have to use picometers for the measurement for an atom.

Facts about Atomic Theory 5: nucleons
Nucleon is the term used to call proton and neutron at the same time. Do you know that nucleus occupies 99.94 percent of the mass in an atom?
Facts about Atomic Theory 6: the number of proton and electron
If an atom has similar number for the electrons and protons, it means that this atom is electrically neutral. You can call it ion if the number of electrons is smaller or bigger than protons. One of the important persons who studies about atom is John Dalton. Get facts about atom here.

Facts about Atomic Theory 7: the chemical elements
By determining the number of protons inside the nucleus, you can find out the chemical element of a certain matter. If you want to know whether this matter is copper or not, you can check the number of proton. All coppers own 29 protons.
Facts about Atomic Theory 8: the mass in the universe
Not all matter in the world is composed of atoms. The unknown type of particles can be seen in the dark matter of the universe.
