Alkaline earth metal is 2nd column in periodic table
Noble gases are last column in periodic table
Chalcogens are oxygen family that is 3rd last column in periodic table
Alkali metal is 1st column in periodic table
Halogens are 2nd last column in periodic table
The diagram refers to 2nd last column in periodic table
So, this is Halogens
Answer: Halogens
