Isotopic and ionic symbols are based on these atomic symbols with numbers and signs added to show mass number, charge, and sometimes atomic number. Recall that the atomic number determines the element, so giving the symbol for the element makes it unnecessary to show the atomic number, but sometimes it is convenient to do so anyway.A  For this lesson, when you work on the practice problems or your problem set to turn in, you should show the atomic number when you write the isotopic symbols. Mass numbers, as we have indicated before, are not the actual mass of the atom, but they are close. Since this superscript is not the number of neutrons, but the mass number (the number of neutrons plus protons), you determine the number of neutrons by subtracting the atomic number (the number of protons) from the mass number. The number of protons (the atomic number) is the same for all atoms of a given element, and can be found on any periodic table.A  All beryllium atoms, for example, have 4 protons.


Had these been symbols for charged ions, the charge would have been included in the usual location a€“ as a superscript following the symbol. Exercise 12 in your workbook will give you some practice writing and interpreting symbols for atoms, ions, and isotopes.A  Be sure and complete this exercise before you move on.
Phosphorus and arsenic, arsenic and selenium, phosphorus and selenium or phosphorus and sulfur? The mass number is the total number of protons and neutrons in the nucleus.A  Each proton and each neutron weighs very close to, but not exactly, 1 amu, hence the mass number is close to the actual mass. It tells you the mass of one atom, how many pieces are inside, and where it should be placed on the periodic table.
