Explain in a paragraph how do you know or can find the number of each subatomic particle using the information on the periodic table. include why the atomic mass of your element on the periodic table is not a whole number or why it is. (PLEASE ANSWER FOR BRAINLEST ANSWER)

A typical atom consists of three subatomic particles: protons, neutrons, and electrons (as seen in the helium atom below). Other particles exist as well, such as alpha and beta particles (which are discussed below). The Bohr model shows the three basic subatomic particles in a simple manner. Most of an atom's mass is in the nucleus—a small, dense area at the center of every atom, composed of nucleons. Nucleons include protons and neutrons. All the positive charge of an atom is contained in the nucleus, and originates from the protons. Neutrons are neutrally-charged. Electrons, which are negatively-charged, are located outside of the nucleus.
