What are atoms made of?
Now that we have talked about how atoms are combined to make other substances, let’s talk about the particles that make up the 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. First, let’s learn a bit about protons and neutrons, and then we will talk about electrons a little later.
Protons and Neutrons
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. 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 (protons are positively charged particles and should repel each other).
