Chlorine is the most reactive gas element. Chlorine is in the halogen family.
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.
Br2 (s) bromine
The halogen gas that is that most reactive of all elements is Fluorine
Radon is a noble gas element and is classified as a nonmetal. It is colorless, odorless, and tasteless, making it difficult to detect without specific testing equipment.
Chlorine is the most reactive gas element. Chlorine is in the halogen family.
Francium is the most reactive metal and fluorine the most reactive nonmetal.
Most elements are non reactive to noble gases.
Chlorine is a NON-METAL. As STP it is a green gas.
No. Helium is a nonmetal but it is completely non-reactive.
Chlorine (halogen), because Argon is a Nobel gas
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.
The fluorine (the element, F) is a gas; no ductility.
The element with the symbol He is helium. It is a nonmetal gas that is colorless, odorless, and tasteless. Helium is the second most abundant element in the universe after hydrogen.
