Periodic table A chart of all known chemical elements Shows all the different types of atoms

Purpose To quickly locate a wide variety of information on a

particular element

How is it organized Organized into rows called periods Organized into columns called groups Arranged in numerical order by the atomic number Also arranged other ways (metals, nonmetals, metalloids, etc)

We use a chart to organize elements called…

Currently scientists believe there are only 98 naturally occurring elements in the universe (Reference link: Chemistry WebsiteWe have also created 20 man-made elements for a total of 118
