There are 18 groups and 7 periods in the modern periodic table.
Group 18, in the Periodic Table, is called the noble gases.
Group-18 belongs to inert elements. The elements attain stability.
The elements that make up Group 18 on the Periodic Table are caleed noble (or inert) gases.

There are 8 elements in the third period of periodic table. The elements belong to group-1,2,13,14,15,16,17 and 18
Stable Elements in the periodic table are located in Group 18 of the periodic table.It is a group of noble gases.Noble gases are considered most stable in nature.
group 18, noble gases
A group in the periodic table is a column of elements that share similar chemical properties due to having the same number of electrons in their outer energy level. Groups are vertical columns and are numbered from 1 to 18.
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.
In Periodic table , Group 18 corresponds to Nobel gas group. They are six elements in this group. Helium , Neon , Argon , Krypton , Xenon , Radon constitute these group. They are chemically inert elements and having stable configuration.
