Group 2 consists of the alkaline Earth metals. The alkali metals are the most reactive metals. What are the three most reactive groups on the periodic table? The most reactive metals are in the first group (vertical column) on the periodic table and are known as the alkali metals. These are (except for hydrogen) soft, shiny, low-melting, highly reactive metals, which tarnish when exposed to air. Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). What are the very reactive metals on the periodic table? Lithium, sodium, and potassium all react with water, for example. The elements toward the bottom left corner of the periodic table are the metals that are the most active in the sense of being the most reactive. As you move down the column, the metals become more reactive because the nucleus gains more electrons and protons (more electron levels), weakening their electrostatic force. What are the 4 most reactive metals?Ä®xplanation: Alkali metals are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). The most reactive metals in the periodic tables are the alkali metals, followed by the alkaline earth metals. What is the most reactive metal family on the periodic table? Francium, however, is a laboratory-produced element and only minute quantities have been made, so for all practical purposes, the most reactive metal is cesium. The most reactive metal on the periodic table is francium. What is the most reactive on the periodic table?Ä. 6 Which is the most chemically active nonmetal on the periodic table?.
