“Are there any elements out their that are nearly completely non-reactive?”
We are about to approach probably one of the most interesting parts of the periodic table, the small but important group known as the noble gases. The nobles gases are very special for one very peculiar fact about them: their outer valence shell is completely filled! This makes them chemically inert, which gives them an extremely nonreactive nature with other elements. Noble gases are called noble gasses because in addition to being colorless, tasteless, odorless, and non-flammable, they also have a low melting and boiling point, which causes them to be gases at room temperature. The elements that make up the noble gases include helium [He], neon [Ne], argon [Ar], krypton [Kr], and xenon [Xe].
