The most reactive metal is is francium, though cesium is often given this title due to francium's extreme rarity and short half life.
The most reactive element is commonly said to be fluorine. But fluorine is a nonmetal.
If by vital you mean most reactive, then the metal francium, Fr, is the most reactive element.
Fluroine is the most reactive non-metal.
Potassium is the most reactive. It is in the 1st group. It is an alkaline metal.
Fluorine is the most reactive non metal.Caesium is most reactive metal in the table.Fluorine has atomic number 9.
Fluorine is the most reactive non-metal element. It readily gains an electron to achieve a stable electron configuration, making it highly reactive.

Potassium is the most reactive element among potassium, iron, and aluminum. It is a highly reactive metal that easily forms compounds by losing one electron to achieve a stable electron configuration.
The metal element that is the most reactive is francium. It is highly reactive due to its low ionization energy and is extremely rare and unstable, making it difficult to study. Francium can react violently with water and air.
Francium is the largest alkali metal, but it is not the largest or most reactive metal overall. It is highly reactive due to its position on the periodic table, which means it will react violently with water and air. However, there are other metals that are more reactive than francium, such as cesium and potassium.
