Argon is what Ar stands for on the Periodic Table of elements.
Ar represents Argon, a noble gas, on the periodic table.
Ar= argon
the AR lies in P-block
Ar stands for Argon. It is inert gas
Elements are found on periodic table. Compounds are not present on periodic table. The table does not contains mixture.Elements can be found on a periodic table. Compounds can be made by bonding two or more elements. But they are not depicted on the periodic table.
Atomic number 18: argon (Ar)
Ar, Arsenic
there is no element with the symbol A. However, Au = gold; Ag = silver; At = astatine; Ac = actinium; Am = Americium; Ar = Argon; As = Arsenic; Al = aluminium
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.
It sounds like they are elements on the periodic table of elements.
Argon (Ar, element number 18) is the last element in the third period of the periodic table.
Argon, Ar, has the atomic number of 18 on the Periodic Table of Elements.
