the AR lies in P-block
Argon is what Ar stands for on the Periodic Table of elements.
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.
It sounds like they are elements on the periodic table of elements.
Atomic number 18: argon (Ar)
Ar represents Argon, a noble gas, on the periodic table.
Calcium is found in the s-block of the periodic table, specifically in group 2.
The elements in the last column of the periodic table, known as the noble gases, are Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn). These elements are gases at room temperature and have full outer electron shells, making them stable and unreactive.
Now (January 2012) the periodic table of Mendeleev contain 118 chemical elements.
Ar= argon
Calcium is in the s-block with the electron configuration of (Ar)4s². It's group is group 2 (calcium earth metal ) in period 4 of the Periodic Table
Ar stands for Argon. It is inert gas
Argon, Ar, has the atomic number of 18 on the Periodic Table of Elements.
