Atoms
are made up of 3 types of smaller particles called sub-atomic particles.
Protons
Positively charged sub-atomic particles found at the center of the atom. The number of these in the nucleus equals the atomic number of the element.
Neutrons
Neutrally Charged sub-atomic particles found at the center of the atoms made up if one proton and one electron. Holds the nucleus together.
Electron
These subatomic particles orbit the neutrons and protons near the speed of light. They are negatively charged and weight 1/1860th as much as proton or neutron
Hydrogen
Name of Element with 1 proton and 1 electron
Nucleus
