Francium (Fr) is the most reactive metal.
Cesium is the most chemically reactive metal.
caesium is the most reactive non-radioactive metal and Florine is the most reactive non-metal, but francium is the most reactive, radioactive metal
Group 1, the Alkali Metals, which are extremely reactive.
Metals which can easily loose electron are most reactive. They are present in group-1.
As you move down the alkali metal group on the periodic table, chemical reactivity increases. This is because the outermost electron in alkali metals is easier to lose as you go down the group, resulting in more reactive behavior with water and air. Lithium is the least reactive alkali metal, while cesium is the most reactive.
The elements from the group 12 are not the most reactive chemical elements.
less reactive.beacuse group-1 elements are the most reactive elements.
Group 17, the Halogens.
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
The alkali metals are the most reactive group of metals on the periodic table. This group includes elements such as lithium, sodium, and potassium, which readily lose their outer electron to form ions in chemical reactions.
Francium is the most reactive metal in group 1 of the periodic table. It is highly unstable and radioactive, making it difficult to study its chemical properties. Francium reacts violently with water and air, similar to other group 1 metals.
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
