What is a rare gas Nov 23, 2017

The noble gas or inert gases refer to the 18 family elements on the periodic table (IUPAC new rules, the original 0 clan).

At ambient temperature and pressure, they are colorless and tasteless single atom gas, it is difficult to chemical reaction. There are six species of rare natural gases, namely helium (he), Neon (NE), argon (AR), Krypton (Kr), Xenon (XE) and radioactive Radon (RN). The OG is an artificially synthesized rare gas with a very unstable nucleus and a short half-life (5 milliseconds). According to law, it is estimated that OG is more lively than radon. However, theoretical calculations show that it may be very lively and not necessarily called inert gas. However, the carbon-family element 鈇 (Fl, formerly provisionally named Uuq) shows similar properties to rare gases.
