neon, argon, krypton, xenon and radon. All of these elements are gaseous at room temperature, colorless, odorless and unreactive with other elements. The noble gases share an electron configuration in which the outer, or valence, atomic orbitals are completely filled. ...
What is noble gas notation? Electron Configuration: The current model of the atom is the quantum mechanical model. In this model, each element has a unique electron configuration. Noble gases are the family of elements that are nonreactive because their valence electrons are full. ...
