I assume you mean "What group does Radium belong to ?"

Radium is a man-made, radioactive element which belongs to the 'rare metals' group which is the second column to the left of the periodic table. All rare earth metals contain 2 electrons in it's outer shell and therefore react violently with Oxygen, Sulphur, Selenium and Tellurium. Radium has 88 Protons, 88 Electrons and 138 Neutrons.
