A proton is a subatomic particle, symbol p or p+, with a positive electric charge of +1e elementary charge and mass slightly less than that of a neutron. Protons and neutrons, each with masses of approximately one atomic mass unit, are collectively referred to as "nucleons".

join or be joined by a chemical bond.
The electron is a subatomic particle, symbol e− or β−, with a negative elementary electric charge
the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table.
An ion is a charged atom or molecule. It is charged because the number of electrons
Macromolecule
A macromolecule is a very large molecule, such as protein, commonly created by polymerization of smaller subunits (monomers).

Acids
Base
An acid is a molecule or ion capable of donating a hydron (proton or hydrogen ion H+)
Bases are substances that accept protons from acids. Let's look at an example. Hydrogen chloride (HCl) is a gas
