Because It has a -4 charge
Flourine, with highest electronegativity value of 4.
It is the most electronegative halogen, meaning it wants electrons the most making it reactive
The most reactive nonmetals are the Halogens, found in group 17. These elements tend to have 7 electrons in their outermost energy level (valence electrons). Since they only need one more electron to stabilize, they react easily to form a negative ion.
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 the most reactive non-metal.
caesium is the most reactive non-radioactive metal and Florine is the most reactive non-metal, but francium is the most reactive, radioactive metal
fluorine is the most reactive non metal in the periodic table.
"very reactive"
fluorine
Carbon is a very reactive nonmetal but not the most reactive.
Flourine is a non-metal, more specifically a gas. Therefore, it does not exhibit the metal property of being malleable.
Fluroine is the most reactive non-metal.
