No, the opposite of that.
The element Californium is reactive.
No, halogens are very reactive elements.
it's stable, but it is a reactive element!
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.
Fluorine is the most reactive element.
fluorine stable fluorine diatomic is unstable
cerium is reactive, if hit with a sharp object it will combust and release nitrogen and hydrogenated carbon. it is the most stable of the rare earth elements though
Fluorine (F) is the most reactive element in group 7A (also known as group 17 or the halogens). It has a strong tendency to gain an electron to achieve a stable octet configuration, making it highly reactive.
Fluorine(F2) is the most reactive element, known to react with even Xenon, Krypton, Gold, Platinum, etc.
Not so reactive !That's why it is called a noble metal.
If by vital you mean most reactive, then the metal francium, Fr, is the most reactive element.
