What Is Inside an Atom Nucleus?

WebbAtoms contain three types of subatomic particles called protons, neutrons, and electrons. Protons carry a positive charge and are found in the nucleus of an atom. The mass of a proton is 1.6726219 × 10-27 kilograms. WebbGiven an atomic number (Z) and mass number (A), you can find the number of protons, neutrons, and electrons in a neutral atom. For instance, a lithium atom (Z=3, A=7 ) contains three protons (found from Z), three electrons (as the number of protons is equal to the number of electrons in an atom) and four neutrons (7 – 3 = 4). pain clinic manitowoc wi
