WebSep 12, 2024 · However, titanium actually is reactive and fine titanium shavings or dust is a fire hazard. The nonreactivity is associated with the passivation of titanium, which is where the metal forms an oxide layer on its outer surface, so the titanium doesn't continue to react or degrade. Titanium can osseointegrate, meaning bone can grow into an implant. WebJan 5, 2024 · In fact, reactivity in chemistry is defined by the number of electrons in the outermost shell. Noble gases (elements like neon and helium) are very unreactive because their outermost electron shells are full. "Since the alkali metals only have one valence electron, they typically achieve this state by giving up that electron.
