In physics, charge, also known as electric charge, electrical
charge, or electrostatic charge. Electric charge is the physical
property of matter/substance which are made up of atoms.
An atom is built with a combination of three distinct particles: electrons, protons, and neutrons. Atom has a center nucleus, where the protons and neutrons are packed together. Surrounding the nucleus are a group of orbiting electrons. The electrons on the outer orbit are valence electrons.
With enough outside force, a valence electron can escape orbit of the atom and become free. Free electron is floating in a space between atoms.
Charge is a property of matter–just like mass, volume, or density. There are two types of electric charges: positive and negative. Charge carriers are atomic particles–specifically electrons (negative charge) and protons (positive charge).
1 C charge is equal to 6.242×1018 electrons.
The charge of an electron is approximately −1.602×10−19 C .
The charge of an proton is approximately +1.602×10−19 C.

Unit
The SI unit of quantity of electric charge is the coulomb (C).1 C charge is equal to 6.242×1018 electrons.
The charge of an electron is approximately −1.602×10−19 C .
The charge of an proton is approximately +1.602×10−19 C.
