  • What is a noble gas on the periodic table?

  • Noble gas. Written By: 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.

  • Why are group 18 elements called noble gases?

  • The Group 18 elements have a particular name Noble gases. Noble gas is translated from the German noun Edelgas, first used in 1898 by Hugo Erdmann (1862 – 1910) to indicate their extremely low level of reactivity. The noble gases were often also called the inert gases, however, since noble gas compounds are now known this name is no longer used.

  • Which element is a noble gas made of neon?

  • They are made of neon, which is a noble gas. Elements that are in Group 18 (VIIIa) of the periodic table are called noble gases. They include Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn).

  • What is the general electronic configuration of noble gases?

  • The general electronic configuration of the noble gases can be written as 鈥榥s 2 np 6 鈥? Therefore, the outermost valence shells of the noble gases can be considered as 鈥榝ull鈥? This is the reason behind the chemically inert nature of the group 18 elements. Helium is a chemical element which is denoted by the symbol He.
