Francium is the most reactive metal and fluorine the most reactive nonmetal.
The halogen gas that is that most reactive of all elements is Fluorine
Fluorine gas, F2
Fluorine.
Fluorine is the most reactive gas on the periodic table. It readily reacts with almost all other elements, including noble gases like helium.
Most elements are non reactive to noble gases.
Fluorine gas is one of the most reactive elements that exist and it will react with most metals.
Oxygen is the most reactive gas in the atmosphere. It readily combines with other elements and compounds to form oxides.
Fluorine is considered the most reactive gas because of its high electronegativity and tendency to gain an electron to achieve a stable electron configuration. It readily reacts with almost all other elements, including noble gases.
Chlorine is the most reactive gas element. Chlorine is in the halogen family.
Flourine is a gas at room temperature, a non-metal, one of the group known as the Halogens and among the most reactive of all the elements.
Fluorine is a gas, yellowish green and is highly reactive.. Fluorine is most commonly found in nature as a fluoride mineral such as fluorite, calcium fluoride
Fluorine is a pale yellow-green gas at room temperature with a pungent odor. It is the most electronegative element, highly reactive and a strong oxidizing agent. Fluorine is the most chemically reactive of all the elements.
