The periodic table organizes the chemical elements by their atomic number. It arranges elements in rows and columns, with each element having a unique symbol and atomic properties that can be predicted from its location on the periodic table. Elements in the same column have similar valence electron configurations and chemical properties, while elements in the same row have similar increases in atomic size. The periodic table is a fundamental tool for understanding chemistry.

2. PERIODIC TABLE The periodic table is your most important tool on the EOC. It organizes information on the elements.

4. The periodic table is made up of rows and columns of elements THE PERIODIC TABLE

10. The elements of the periodic table can be divided into three main categories: metals, nonmetals and metalloids. Jlab.org

11. Elements in the periodic table are also grouped into families (groups), which are the columns. Elements in families have similar properties Jlab.org

12. The elements are also categorized into periods, or horizontal rows. Jlab.org
