The noble gases (historically the inert gases, sometimes referred to as aerogens) are the naturally occurring members of group 18 of the periodic table: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).
noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og). The noble gases are colourless, odourless, tasteless, nonflammable gases.
May 23, 2020 · The noble gases are the elements in group 18 on the periodic table. Atoms of these elements have filled valence electron shells, making them relatively inert, colorless, odorless, monatomic gases at room temperature and pressure.
May 30, 2019 · The noble gases are group 18 on the periodic table, which is the column of elements on the right side of the table. There are seven noble gas elements: helium, neon, argon, krypton, xenon, radon, and oganesson. Noble gases are the least reactive chemical elements.
Sep 14, 2019 · These elements are noble gases, sometimes called inert gases. Atoms belonging to the noble gas group have completely filled their outer electron shells. Each element is non-reactive, has high ionization energy, electronegativity near zero, and a low boiling point.
The noble gases—most often helium and argon, the least expensive—are used to provide chemically unreactive environments for such operations as cutting, welding, and refining of metals such as aluminum (atmospheric oxygen and, in some cases, nitrogen or carbon dioxide would react with the hot metal).
What would the noble gas electron configuration for an element look like if the element is a noble gas? Would it be. [Ar] or. [Ne]3s^23p^6 ? •. ( 16 votes) Upvote.
