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
The two most reactive groups of elements in the periodic table are the alkali metals and the halogens. Halogens are nonmetals located in group 17 of the periodic table and include elements like fluorine, chlorine, and iodine.
There are 18 groups in the periodic table of elements.
Noble gases are least reactive because they have a full shell
they
Group 18, also called the noble gases, contains the elements that are nonreactive.
