there are many non metals that are very very reactive. some are even more reactive than some certain metals. there are no exact answers to that but according to me, it should be fluorine.
HOPE THIS PIECE OF INFORMATION PROVES TO BE USEFUL
fluorine
Yes, very reactive, more than silicon, nitrogen and sulfur (neighbours in periodic table. But it is not the most reactive nonmetal, which is fluorine.
helium is a non reactive gas at room temperature
The most reactive NON-METAL is Fluorine. It is found in group 7, period 1. It is the most reactive non-metal because there is a strong electrostatic force, as there are no shells of electrons shielding the force therefore strong force enables the nucleus to attract another electron so that the outer-electron shell is FULL and the atom can become stable. Fluorine is diatomic, (eg. exists in pairs), so the symbol for Fluorineis F2
Sodium is by far the most reactive. It self ignites in air (it is stored in oil), reacts vigorously with water (releasing hydrogen) and reacts explosively in acids-even dilute. But the most reactive metal is Cesium and the most reactive non-metal is Flourine Cesium and H20 will explode...
Hydrogen is displaced from acid when you add a reactive metal.
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.
Fluroine is the most reactive non-metal.
fluorine
Gold is a less reactive metal but not non-reactive; all metals are reactive.
The most reactive non-metal is fluorine. It is often nicknamed the 'Tyrannosaurus Rex' of the elements because of its reactivity. NB . Oxygen ,which we breath, is also a very reactive element. If it wasn't so reactive we would probably die.
The most reactive metal on the table is Caesium. Fluorine is the most reactive non-metal on the table. For metal periods, reactivity decreases from left to right. Non-metals are the opposite.
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.
