Inorganic Ventures provides an interactive periodic table. This periodic table guide breaks down the elements name, atomic weight and oxidation state.

Of the main group elements, fluorine has the highest electronegativity (EN = 4.0) and cesium the lowest (EN = 0.79). This indicates that fluorine has a high tendency to gain electrons from other elements with lower electronegativities. We can use these values to predict what happens when certain elements combine. The following video shows this. When Dmitri Mendeleev created the periodic table in the late 19th century, he grouped elements by atomic weight. When grouped by weight, the behavior of the elements appeared to occur in regular intervals or periods. The columns of the modern periodic table represent groups of elements and rows represent the periods.
