Define noble gas and name all the Nobel gases |
|
Answer» On the far right side of the periodic table, in group 18, is a unique group of elements known as the noble gases. The noble gases are a group of extremely nonreactive elements that all exist in the gas state. They are inert. Inertness refers to an element\'s tendency to resist change and reactions.The noble gases include helium, neon, argon, krypton, xenon, and radon.\xa0 The noble gases (historically also the inert gases) make up a group of chemical elements with similar properties; under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity. The six noble gases that occur naturally are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn). Oganesson (Og) is variously predicted to be a noble gas as well or to break the trend due to relativistic effects; its chemistry has not yet been investigated. |
