what is the group of the most radioactive metals
Quick Answer. The most reactive group of metals on the periodic table are the alkali metals. These metals are so reactive that they are not found naturally by themselves; they are found in nature as parts of compounds. The alkali metals consist of the elements lithium, sodium, potassium, rubidium, cesium and francium. These elements have a single electron in their outermost electron shells. To become more stable, atoms want to keep eight electrons in these outermost shells.
