atomic number 2,He,helium- a very light colorless element that is one of the six inert gasses; the most difficult gas to liquefy; occurs in economically extractable amounts in certain natural gases (as those found in Texas and Kansas) ...
What are the properties of noble gasses? Noble gases have similar physical and chemical properties. These include low melting point, low boiling point, colorless, odorless, nonflammable, and low reactivities. Are noble gases reactive? Noble gases have a low reactivity. It was once thought that th...
Noble gasses are gasses that are chemically inert. This means that they are not capable of forming chemical bonds naturally due to the fact that they have zero valence electrons. Elements:On the periodic table, elements are organized according to groups (placed in columns) with other elements ...
Referring to the periodic table, what are the noble gasses?Which of the following species have ground-state noble-gas electron configurations? (a) Al^{2+} (b) K^{2+} (c) N^{3-} (d) I^{2-} (e) P^{3+}Which of the following is not a noble gas? a. nitrogen ...
no. Because only the other five had completed their atomic structure. Helium has only two valance electrons. it will react with other gasses to obtain the octet structure. Byobsessedwithloopy— On Jun 10, 2009 Noble gases are also referred to as rare gases, even though some are really not...

In chemistry, the noble gases are a set of chemical elements that share similar characteristics and properties. There are six naturally occurring noble gasses, which are helium, neon, argon, krypton, xenon, and radon.Answer and Explanation: ...
