The Electron Theory

Electron Theory states that all matter is related to electricity. What makes it related to electricity?

Matter is anything that occupies space, it is everything around you! Matter includes the air we breathe, water, paper, copper... practically everything. A matter could be an element or a compound.

Elements are the basic structure of nature. These are materials that can not be reduced to a simpler one by chemical means. As of this writing, there are about 117 known elements 94 of which occur naturally on Earth. Examples of elements are the hydrogen, carbon, copper, gold, silicon and many more. The smallest particle of an element that retains the chemical properties of the element is called atom.

Compound is a chemical combination of of two or more elements. Example of compounds are the table salt (NaCl), combination of sodium and chlorine; water (H2O), combination of hydrogen and oxygen and many more. Smallest particle of compound that still retain the chemical properties of the said compound is called molecule.

Atom is basically made up of tiny particles called electron, proton and neutron. The dense central portion of atom is the nucleus, where protons and neutrons are located. Protons are the positively charged particle of the atom while neutrons are electrically neutral. Revolving around the nucleus are the negatively charged particle called electrons. Atoms in its normal state contain the same number of electrons and protons hence atom is said to be electrically neutral. When a normal atom losses electrons the atom becomes positively charged (protons are greater than electrons). Atoms which gain electrons become negatively charged (electrons are greater than proton).

Let's go back to the question, what makes matter related to electricity? The answer is very simple... it's because all matter contains negatively and positively charged particles, the electrons and protons.
