The Periodic Table

The periodic table is used to group elements with similar properties together. Each box on the table contains the symbol for an element. Elements in the same column are similar to each other.

For example, the elements in the first column are called the alkali metals. These metals react with water to form hydrogen gas. This is an example of a chemical reaction.

The last column of the periodic table consists of the noble gases. The noble gases are called noble because they seldom react with anything.

The transition metals make up the middle block of the periodic table. Like the other elements that are grouped together (alkali metals, noble gases), these metals have very similar properties. Professor Stahl and his research group work with many of the transition metals. Below is a picture of the periodic table.
