It is in Group O or Group 8. Also known as noble gas, they do not react with other elements as they do not have to react to get a stable configuration.
There is no group number to Uranium though its group name is Actinide.
Radium belongs to Group 2 of the periodic table, also known as the alkaline earth metals.
Radon belongs to the group of noble gases on the periodic table.
selenium is in the group IV so it belongs to the Chalcogen family :)
It belongs to the amine group or family.
Argon is a noble gas element. It belongs to period 3, group 18.
There is no group number to Uranium though its group name is Actinide.
The group that argon belongs to is the Noble Gases, otherwise known as the inert gases. However, Noble gases is the more acceptable term nowadays because the description inert implies that they cannot be reacted with. These Noble Gases such as argon can be reacted with, but they need incredibly extreme conditions to do such.
Noble or inert gases
