The mass number (A) is the sum of the number of protons (atomic number, Z) and neutrons. There are 118 elements in the periodic table and the 78th of these elements is platinum. Based on the atomic number, mass number, and neutron number of the element, three things can be considered. Element: A pure substance that cannot be broken down into a simpler substance by chemical means. So, if the cation has 10 electrons, the neutral atom must have had 13 electrons because losing 3 of those results in a charge of 3+. Phosphide ion (P3-) = Phosphorus atom + 3 electrons P3- = P + 3e- Thus, phosphide ion has same number of protons and neutrons as phosphorus atom but has three electrons more. Therefore, Ca has 20 protons. Adding a proton to an atom makes a new element, while adding a neutron makes an isotope, or heavier version, of that atom. Also discussed is the position of electrons, protons, and neutrons in an atom, the number of atomic masses, and the isotopes of platinum. Using the periodic table, identify the lightest member .
