Which element have zero valency?
Noble gases were considered elements with zero valency; but today a significant number of noble gases (especially xenon) are known.
What are some other names for Noble gases?
Another name for noble gases is inert gases.
Why elements of group 18 are zero valent?
because they have completely filled orbitals (or shells). hence generally are inert
Which is the least reactive Mg Li or Be?
Be is least reactive its outermost orbital 2s is completely filled so its electron affinity is almost zero.
How reactive are the elements in noble gases?
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.
What group of element is the most unreactive?
Zero group elements are least reactive. Its The Noble Gas Family which is helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn).
Which group on the periodic table does not react with any other elements?
The noble gas family consisting of Helium, Neon, Argon, Krypton, Xenon and Radon have been considered as non-reactive and inert due to their stable configurations. But now compounds having Xenon and Krypton have been synthesized. So, it can be said that there is no such family on the periodic table which does not react with elements.
Least reactive alkaline earth metal?
All alkali (not alkaline-earth) metals are extremely reactive with water, but within the group, lithium is the least reactive.
What is the power factor of AC generator when the reactive power is equal to zero?
Per factor is 1 when reactive power is zero.
Which element have zero valency?
Noble gases were considered elements with zero valency; but today a significant number of noble gases (especially xenon) are known.
What are Zero group elements?
The Group 0 elements are called the noble gases. These are the six gases that are almost completely inert. Since they do not lose or gain any electrons, their valence is 0.
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.
What are some other names for Noble gases?
Another name for noble gases is inert gases.
Why are a select group of elements referred to as the noble gases?
These are called noble or inert gases because their oxidation number of zero makes them least reactive which is due to maximum number of electrons possible in their outer shell..because they generally do not combine with other atoms to form compounds
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 column in the periodic chart contains the atoms with an ideal electron configuration?
I think you mean the Ideal or Noble gases. Column 18 , or '8' , in 'old money'.
Why elements of group 18 are zero valent?
because they have completely filled orbitals (or shells). hence generally are inert
