Nitrogen is a group 5A element that is highly reactive and essential for plant growth.
fluorine stable fluorine diatomic is unstable
Potassium is the most reactive element among potassium, iron, and aluminum. It is a highly reactive alkali metal that readily reacts with water and air. Iron is moderately reactive, while aluminum is reactive but forms a protective oxide layer that prevents further reaction with the environment.
Yes, iodine can displace bromine in a chemical reaction because iodine is more reactive than bromine. When a more reactive element comes into contact with a compound containing a less reactive element, it can displace the less reactive element from the compound.
A single displacement reaction is a type of chemical reaction where a free element replaces another element in a compound. This occurs when a more reactive element displaces a less reactive element in a compound, forming a new compound and releasing the displaced element.
Fluorine is the most reactive element.
The element Californium is reactive.
Hydrogen is not only the lightest element of all, it is also very reactive.
Fluorine(F2) is the most reactive element, known to react with even Xenon, Krypton, Gold, Platinum, etc.
An element is said to be chemically reactive when it combines with another element. These two elements will create a new compound.
If by vital you mean most reactive, then the metal francium, Fr, is the most reactive element.
Potassium is most reactive with the element Oxygen. However, it should be noted that it is most reactive with a non-element: Water.
copper is very un-reactive. lead is more reactive.
Pretty much every element, apart from platinum and Gold. Elements in groups 1 (alkali metals) and 2 (alkaline earth metals) are usually the most reactive.
Fluorine
XENON
Yes. it is.
