Which alkali earth metals are radioactive in nature

1.	Which alkali earth metals are radioactive in nature
Answer» ONG>ANSWER: Radioactivity. All of the alkaline earth metals, except magnesium and strontium, have at LEAST one naturally occurring RADIOISOTOPE: beryllium-7, beryllium-10, and calcium-41 are trace radioisotopes. Calcium-48 and barium-130 have very long half-lives and THUS occur naturally. All isotopes of radium are radioactive.
