How many valence electrons in radium
WebRadium. It is the heaviest of the alkaline earth metals. It is extremely radioactive. It resembles barium in chemical behavior. It is found in pitchblende, a uranium ore. It reacts violently to water and oil and forms radium hydroxide, which is more unpredictable than barium. Recently discovered radioisotopes are much more powerful and safer to ...
