What does VIII mean on the periodic table?

VIII on the periodic table represents Group 8, also known as the noble gases. This group includes elements such as helium, neon, argon, krypton, xenon, and radon. Noble gases are known for their stable properties and reluctance to bond with other elements.


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.


What group consists of very unreactive gases?

Noble gases, such as helium, neon, argon, krypton, xenon, and radon, are known as very unreactive gases. They are characterized by having a full outer electron shell, which makes them stable and less likely to form chemical bonds with other elements.


How many unpaired electrons does krypton have?

This is a chemical element. You can find the how many electron in a single atom by using a periodic table.


The common ion charge of some elements in the periodic table is zero what does that tell you about the element?

An element with a common ion charge of zero means that it typically forms neutral atoms. This means that the number of protons in the nucleus is equal to the number of electrons surrounding the nucleus, resulting in a stable, electrically neutral element.

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.


What is helium's position on the periodic table?

In 18th group (zero group), 1st period. It is the first noble gas.

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.

Oxidation number of groups in periodic table?

Group 1 elements have an oxidation number of +1, group 2 elements have an oxidation number of +2, group 17 elements have an oxidation number of -1, and group 18 elements (noble gases) have zero oxidation number since they are chemically unreactive.


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.


What makes group 18 on the periodic table special when bonding?

Group 18 is the Noble Gas Family. Since the outer energy level of all elements in the family are full they never bond except at extremely cold temperatures close to absolute zero.


How do you find the oxidation number using the periodic table of elements?

To find the oxidation number of an element using the periodic table, you need to consider the group number for main group elements and the charge on transition metals. Main group elements typically have oxidation numbers equal to their group number, while transition metals can have multiple oxidation states indicated by Roman numerals in parentheses. Exceptions like oxygen (-2) and hydrogen (+1) exist, and the sum of oxidation numbers in a compound must equal zero.


What is the block to which the inert gases belong to?

The inert gases belong to the p-block of the periodic table. Specifically, they are located in Group 18 (VIII A) and consist of Helium, Neon, Argon, Krypton, Xenon, and Radon. They are characterized by their stable electron configurations and lack of reactivity.
