Reactive nonmetals
WebNonmetals are typically poor conductors of heat and electricity, with low melting and boiling points. They tend not to be malleable or ductile, so they form brittle solids. Nonmetals … WebJun 7, 2024 · The most reactive nonmetals reside in the upper right portion of the periodic table. Since the noble gases are a special group because of their lack of reactivity, the element fluorine is the most reactive nonmetal. It is not found in nature as a free element.
