Subatomic Particles
Atom
Particles that are smaller than the atom are called subatomic particles. The three main subatomic particles that form an atom are protons, neutrons, and electrons. The center of the atom is called the nucleus.
-Protons and neutrons make up the nucleus of an atom. All protons are identical to each other, and all neutrons are identical to each other. The number of protons and neutrons in the nucleus give the atoms their specific characteristics. Atoms also have Electrons that orbit around the nucleus in a place called the "Electron cloud"
--Protons have a positive electrical charge, so they are often represented with the mark of a "+" sign.
--Neutrons have no electrical charge and are said to help hold the protons together.
--Electrons have a negative charge, often represented by a "-" sign.
