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

The least active elements are the .?
Generally, the least reactive elements are the noble gases.
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 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.
Are noble gases group IV?
No. noble gases are group VIIIA or group 18 elements
What are the elements in Group 17-18 called?
The Group 18 elements are called the noble gases or sometimes inert gases. Wikipedia has information on the noble gases, and a link is provided.
The least active elements are the .?
Generally, the least reactive elements are the noble gases.
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 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.
The elements that do not ordinarily form compounds are?
Noble gases do not normally form compounds.
Are noble gases active elements?
No.
What are the least elements?
The Noble 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.
Are noble gases group IV?
No. noble gases are group VIIIA or group 18 elements
What are elements that rarely combined with other elements are?
The noble gases.
What family is group 18 on the periodic table of elements?
The Noble Gases-because they rarely combine with other elements and are found only as uncombined elements in nature.
