Protons and Neutrons in Helium. Helium is a chemical element with atomic number 2 which means there are 2 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.
These periodic tables use accurate data for name, atomic number, element symbol, atomic weight, and electron configuration, obtained from the International Union of Pure and Applied Chemistry or IUPAC. What we’ve done is list the tables, along with links, so you can get detailed info about each one.
Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas!
Drag protons, neutrons, and electrons onto the atom template to make an atom of your element. State the numbers of protons, neutrons, and electrons in your atom, as well as the net charge and mass number.
