Web23 de jul. de 2024 · The periodic table that we use today contains seven periods and 18 groups. This design lets you quickly find an element’s symbol, atomic number, and atomic mass. The table can also give you information on chemical properties. For example, elements on the left-hand side of the periodic table are generally metals. Webexample, the element carbon—shown as ‘C’ on the periodic table in Figure 2—has three common isotopes. All three have six protons, but each has different numbers of neutrons: one has six, one has seven, and one has eight neutrons. A useful shorthand for isotopes consists of the chemical symbol
