Radium is the heaviest known alkaline earth metal and is the only radioactive member of its group.
Explanation:
Radium is a chemical element with the symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. Pure radium is silvery-white, but it readily reacts with nitrogen on exposure to air, forming a black surface layer of radium nitride.
Radium is used in luminous paint (in the form of radium bromide). Radium and beryllium were once used as a portable source of neutrons. Radium is used in medicine to produce radon gas, used for cancer treatment.
Most are due to gamma radiation, which can travel a long way through the air. Just being near high levels of radium is dangerous. Radium is a known cancer-causing substance. Exposure to high levels of radium can lead to higher chances of bone, liver and breast cancer.
