The Perioduic Table

Chemists have arranged the chemical elements into a table called the periodic table. This helps us to make sense of the different properties of the elements and their compounds. It also helps us to predict how they will behave in different situations.

There are several different versions of the periodic table, but all have a similar appearance. Each element is shown by its symbol, and sometimes also by its name.

In the periodic table, the elements are arranged in order of proton number, also called atomic number. This is the number of positive protons in each atom. The proton number is shown, written underneath each element in the table below.

Putting elements in this order gives a repeating pattern of their properties. In the periodic table each element is placed beneath those with similar properties.
