Figure 5: The Periodic Table of Elements Thiscontroversyover defining themolecan seem a little strange. After all, the mole is not a term we need to refer to most things in daily life (such as gray squirrels!). But as we’ve seen in this module, the mole is very useful for scientist...

To calculate a formula mass first determine which elements are present in the formula and use the subscripts in the formula to determine how many of each element are present. Next, find the mass of each element from the periodic table and multiply the mass by the number of each element. Fi...
You can locate the atomic mass of an element on the periodic table, which lists all known elements. The atomic mass is the number listed directly below the symbol for the element on the periodic table. Atomic mass is given in atomic mass units, or amu, which are used to measure very sm...
Since both neutrons and protons have almost unit atomic masses, the atomic mass of a nuclide should be close to the number of nucleons, i.e. the mass number. However, when the table of elements in the periodic system (Appendix I) is studied it becomes obvious that many elements have ...
Periodic Table of Elements - The periodic table is the tabular arrangement of all the chemical elements on the basis of their respective atomic numbers. In the periodic table, the vertical columns are called groups and the horizontal rows are called peri
