The most reactive elements on the periodic table are the alkali metals. Starting just under Hydrogen on the far left of the table is the first alkali metal atomic #3 Lithium, #11 Sodium (the fun metal :o), and so forth and so on down the column to atomic #87 Francium. science teacher

How elements are grouped in columns in the periodic table?
There are 18 groups in the Periodic Table of elements.
How are the elements arranged?
Elements are arranged on the periodic table based on their atomic number, which is the number of protons in their nucleus. This arrangement groups elements with similar properties in columns called groups or families, while elements in the same period have the same number of electron shells.
