2 Element of the Solar System.jpg Elements of the Solar System ….current measurements indicate that 75% of the mass of the Universe is in the form of hydrogen, 24% in the form of helium and the remaining 1% in the rest of the periodic table (note that your body is made mostly of these `trace' elements). Element of the Solar System.jpg Elements of the Solar System Its harder and harder to make nuclei with higher masses (because more protons mean more positive charge and more electrostatic repulsion). So the most common substance in the Universe is hydrogen (one proton), followed by helium, lithium, beryllium and boron (the first elements on the periodic table ). Stars are element factories… Nomenclature (Elements, Isotopes) A X Z N Z is the atomic (proton) number N is the neutron number A is the mass number (N+Z) X is the chemical element symbol The atom A neutral atom contains an equal number of Z protons in the nucleus and Z electrons in the electron shell.
