These are the "noble gases." They are chemically inert, because they have a full octet of electrons in their valence energy level. Therefore, they do not need to lose or gain electrons to achieve stability; rather, they are naturally stable, which is why they do not react.
A column is known as a group in periodic table. There are 18 groups in the modern setting of periodic table. Elements in the same group usually share same chemical properties and striking physical characteristic trends.
The noble gases are in column 18 of a wide form periodic table.
The columns of the periodic table are called groups.
Helium is located on the group 18 and period 1 on the modern periodic table.
There are no 'rows' on the Periodic Table of the Elements.I assume you are talking about Group-18 of the table.Group-18 of the Periodic Table of the Elements are the noble gases. These elements have a full valence shell (8 electrons).

Noble Gases
Group 18, in the Periodic Table, is called the noble gases.
A group, there ae 18 of them.
Group 17 elements (Gr. 17 are not metals.) are called halogens (halogen group).
The noble gases are in column 18 of a wide form periodic table.
There are 18 groups on the periodic table.
The columns of the periodic table are called groups.
Group 1 is called the alkali metals, while Group 18 is called the noble gases.
A group is vertical column. There are 18 groups in periodic table.
