This affirmation is not correct.
noble gases
Elements in the same group or column on the periodic table have similar chemical properties. Helium is in group 18 or the Nobel gases. Elements with similar chemical properties would be the rest of the elements below Helium Neon, Argon, Krypton, Xenon, and Radon
the noble gases are positioned on the last column on the right. As the elements descend down the column they are more reactive
No, the noble gases are the elements in the far right column (vertical).
Except noble gases the groups of elements in periodic table have the similar chemical properties but not the physical.
noble gases, or inert gases they are the same thing and they are group 18 they have full valence electrons so they are unlikely to react with other elements

The answer is: noble gases
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.
The last column of the periodic table of elements
I think you mean the Ideal or Noble gases. Column 18 , or '8' , in 'old money'.
the noble gases are positioned on the last column on the right. As the elements descend down the column they are more reactive
No, the noble gases are the elements in the far right column (vertical).
Column 18, or in older tables, column VIII, the noble gases.
Except noble gases the groups of elements in periodic table have the similar chemical properties but not the physical.
If they are placed in the same vertical column, which is called a group, it means that they have similar properties. For example, the first column (group) of the periodic table are the alkali metals. The second is alkali earth metals. Other groups include halogens, royal gases, etc.
