The answer is: noble gases
The last column of the periodic table of elements
This is probably a reference to the periodic table of the elements, which has columns. All the elements in a given column have the same configuration of valance electrons. There is a column of noble gases, a column of halogens, etc.
All of the elements in column 18 of the periodic table are noble gases. This means their outer electron shells are completely full and in most cases are inert.
Column 18, or in older tables, column VIII, the noble gases.
The noble gases, column 18 in the most common modern periodic table.
To find the information on certain elements!!Periodic Table lists elements in the increasing order of atomic number.Since elements are grouped in to columns (eg:inert gases), it is easier to predict the chemical behaviour of various elements.
the noble gases are positioned on the last column on the right. As the elements descend down the column they are more reactive
The halogens, column 17.
Group 18 on the Periodic Table contains the Inert Gases. Inert Gases tend to be unreactive. This group has the elements Helium, Neon, Argon, Krypton, Xenon, and Radon.
Inert gases, or noble gases, make up the 18th column on the periodic table. The names of the gases (in order from top to bottom) are: helium, neon, argon, krypton, xenon, radon.
The elements in column 18 of a wide form periodic table or Column VIII of a narrow form periodic table, commonly called the noble gases. Also, both elements in the first period, the elements in groups 15, 16, and 17 of the second period, and the element in group 17 of the third period.
The noble gases, in group 18 (the far right column), are mostly inert.
