What does VIII mean on the periodic table?
it means group zero
What group consists of very unreactive gases?
Noble gases are unreactive. They are all in the far right column (group). Depending on the Periodic Table that you look at, it may be labeled group zero or group 18.
How does Helium belong to Group 8 in the periodic table but not belong?
Firstly, helium does NOT belong to group 8. In the periodic table used until around the 1960s, helium belonged to group zero. Iron cobalt, and nickel families shared group VIII. In the modern, iupac sanctioned periodic table, the noble gas family -- helium, neon, etc. -- are in group 18. I think the reason your teacher (? or textbook, or whoever) has asked this question is because all of the other noble gases have 8 electrons in their outermost shell, while helium has only 2.
The common ion charge of some elements in the periodic table is zero what does that tell you about the element?
That it does not gain or loose electrons.
What is a zero order table in statistics?
A zero-order table is simply a table showing variables controlled for. As an example, given an equation of two variables, this table shows the values that result from the available values for those two variables.
What does VIII mean on the periodic table?
it means group zero
What is helium's position on the periodic table?
In 18th group (zero group), 1st period. It is the first noble gas.
Why is the group consisting of noble gases labeled as zero group?
They were once labeled group 0 in the periodic table because it was believed they had a valence of zero, meaning their atoms cannot combine with those of other elements to form compounds.
Is Family of noble gases named as zero-group?
They were once labeled group 0 in the periodic table because it was believed they had a valency of zero, meaning their atoms cannot combine with those of other elements to form compounds.
What group consists of very unreactive gases?
Noble gases are unreactive. They are all in the far right column (group). Depending on the Periodic Table that you look at, it may be labeled group zero or group 18.
How many elements on the periodic table contain living organisms?
zero
What are the defects in mendeleev's periodic table?
His periodic was not in complete accordance with what he was classifying with i.e classification with respect to ascending atomic mass. here is an example: the atomic mass of the Ar is 39.9 and that of sodium is 39 but he placed Ar in the zero group and Na in the 1st group. this is one example. his periodic table had some more defects like this. this defect was observed when the true atomic masses were known. In his time the true atomic masses were not known. This was one of the reason for the failure of his periodic table.

What is the oxidation number for Li?
Every element on the Periodic Table has an OXIDATION NUMBER of zero, including Lithium.
Can elements in the middle of the periodic table bond with other elements?
All the elements except elements belonging to zero group (He, Ne, Ar, Kr and Xe which are inert in nature) can bond with other elements.
The common ion charge of some elements in the periodic table is zero what does that tell you about the element?
That it does not gain or loose electrons.
What elements have no valency?
The noble gases, or group 18 elements, have oxidation states of zero. However, their chemistries are not as barren as one might expect. Please see the link for the periodic table and individual articles for these elements.
