There are six noble gases: helium, neon, argon, krypton, xenon and radon

The six noble gases are found in group 18 of the periodic table.
It is found in group 18 (the group on the extreme right)
column of the periodic table.
group 18 on the periodic table
Noble gases are found in group 18 of the periodic table.
Noble gases were not discovered when Mendeleev formulated his periodic table in 1869. Hence noble gases were not shown in the periodic table of 1869.
They are the family that is the furthest to the right of the Periodic Table.
Noble Gases
Because noble gases were not discovered when Mendeleev formulated his periodic table
Noble gases can be found in group 8 on the periodic table (column farthest to the right). They have 8 valance electrons in their outer shell and therefore do not react with anything. This made it hard for scientists to discover them.
