In the old definition zero.
He has a full electron shell- no valence electrons
the others all have octets, ns2np6
With neon this gives a full shell- there are no known neutral chemical compounds for He and Ne
For the heavier noble gases the outer shell is only partly filled they have empty d orbitals for example. - which rationalizes why there are compounds known for all of these
What else can I help you with?
The least active elements are the .?
Generally, the least reactive elements are the noble gases.
Are noble gases group IV?
No. noble gases are group VIIIA or group 18 elements
What is the state of the noble gas family?
All noble gases elements are gases.
What are five elements that are noble gases?
I think it would be easier to say what gases ARE noble gases. The six noble gases are Helium, Neon, Argon, Krypton, Xenon, and Radon. Any other elements are not Noble gases. This can include elements like Gold, Mercury, Calcium, Potassium, and barium.
Elements that do not typically react with other elements are known as?
Elements in the Periodic Table that are not reactive are called the Noble Gases.
What are the elements in Group 17-18 called?
Group 17 elements are called halogens, which include fluorine, chlorine, bromine, iodine, and astatine. Group 18 elements are called noble gases, which include helium, neon, argon, krypton, xenon, and radon.
The least active elements are the .?

What is the state of the noble gas family?
All noble gases elements are gases.
What are group 18 elements in the periodic table called?
Noble gases.
What class of element includes all of the elements that are gases at room temperature?
The class of elements that includes all elements that are gases at room temperature is the noble gases. These are located in Group 18 of the periodic table and include elements such as helium, neon, argon, krypton, xenon, and radon.
