Atoms of these elements do not combine with other atoms, even atoms of the same element, because their valence electron shells are full.

Which atom has atomic number zero and mass number zero?
No sense; atomic number zero and atomic weight zero doesn't exist ! Edit: !Answer = 0
What element has the lower atomic number of any group?
Trick question? Lowest group is 1? There is no zero. If it's not a trick question then it's Hydrogen.
Why does ammonium belong to group zero?
NH4+ is kept in group zero of qualitative analysis because it is the only non metalliccation. . its test is quite different than that of other cations.it does not resemble any other cation so it tested first of all in zero group .the reagent for zero group is Na OH solution.if it is not tested in zero group then in the subsequent groups we use NH4 OH asreagents. then the solution will automatically contains NH4+ ion if it would havenot been present in the original mixture to analysed.SO IT IS EVIDENT THAT THE NH4+SHOULD BE KEPT IN ZERO GROUP.
Why does an atomic number increase?
If you mean looking at the next element on the table then the mass would increase. However, the atomic number is only the number of protons in an atom and is not a true indicator of atomic weight. Variations in Neutron count can cause differences in atomic weights.
What is hydrogen's number of neutrons equals mass number - atomic number equals?
A hydrogen atom has one proton, one electron and '''zero''' neutrons. Rephrased, the question is: Hydrogen's number of neutrons equals mass number - atomic number.
What are some other names for Noble gases?
Another name for noble gases is inert gases.
How are elements indentified on the periodic table?
Elements in the table are identified by different things. What they are made of, atomic mass, and atomic number. Elements can also be identified by what state of matter they are at zero degrees Celsius and standard pressure which 1atm. The most current, standard table has 117 different elements.
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 is argons group?
Atomic number of argon is 18, and it belongs to group 18 , a group of noble gases , it has 8 electrons in the outermost orbit and therefore a zero valancy.
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.
Which atom has atomic number zero and mass number zero?
No sense; atomic number zero and atomic weight zero doesn't exist ! Edit: !Answer = 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.
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 element has the lower atomic number of any group?
Trick question? Lowest group is 1? There is no zero. If it's not a trick question then it's Hydrogen.
Why elements of group 18 are zero valent?
because they have completely filled orbitals (or shells). hence generally are inert
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 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).
