Argon is what Ar stands for on the Periodic Table of elements.
Argon belongs to the noble gas family on the periodic table.
Argon is a noble gas located in group 18 (or 8A) of the periodic table.
Argon is an element of the periodic table.
A group in Periodic Table is the column of element in periodic table
Beryllium is in column 2 of a wide form periodic table and column II(A) of a narrow form periodic table.
Argon (Ar, element number 18) is the last element in the third period of the periodic table.
The 18th column on the periodic table is the noble gases (Helium, Neon, Argon, Krypton, Xenon, Radon. They have their shells filled up and do not normally react with other elements that easily.
Helium belongs to the noble gas family, along with elements like neon, argon, krypton, and xenon. These elements are characterized by their low reactivity and full outer electron shells, making them stable and non-reactive.
