Electrons
Today, everybody uses a cellular phone.
The core of a cellular phone is electricity. Without electricity or a battery, it is nothing. But, it is just 115 years since mankind identified physical existence of electrons whose flow in quite a huge number is electric current, namely electricity.
In 1896, the British physicist J. J. Thomson, with his colleagues John S. Townsend and H. A. Wilson,[11] performed experiments indicating that cathode rays really were unique particles, rather than waves, atoms or molecules as was believed earlier. Thomson made good estimates of both the charge e and the mass m, finding that cathode ray particles, which he called "corpuscles," had perhaps one thousandth of the mass of the least massive ion known: hydrogen. He showed that their charge to mass ratio, e/m, was independent of cathode material. He further showed that the negatively charged particles produced by radioactive materials, by heated materials and by illuminated materials were universal. The name electron was again proposed for these particles by the Irish physicist George F. Fitzgerald, and the name has since gained universal acceptance.This discovery has led to development of modern technology. Discovery of just one physical entity called electron has made today's material civilization possible.
Electrons are everywhere, though most of them are bound to atom cores or atomic nuclei without flowing outside and thus without becoming electric current.
As an atom has a size or a volume, a man has a size or a volume, since the human body is made of atoms and only atoms in a sense, though there are hundred types or so of atoms..
The electrical strength and the mass of an electron is well known through rigorous scientific experiments. But, its size is yet to be determined. A standard theory regards it as zero, but it can have a finite volume.
Size of an atom: 1 x 10^-10 =1/10000000000 meters
Size of a nucleus: 1 x 10^-15 = 1/1000000000000000 meters
Planck's length: 1.6 x 10^-35 meters
Schwarzschild radius: 1.3 x 10^-57 meters
Of course, such a tiny entity never knows that it is used for your mobile phone, PC, TV, or electricity.
A lightning discharge consists primarily of a flow of electrons.The electric potential needed for lightning may be generated by a triboelectric effect.
And when you examine anything, a stone, a plant, an animal, a man, a cellular phone, chemicals, and clothes, you will find that they are all simply made of electrons and atomic nuclei (protons and neutrons) and made of them only. But, how can these three types of materials, electrons, protons and neutrons, make so many various matters and products is a true wonder.
In other word, you need only three elements to make everything.
