beryllium | recycled oceanic element | Silvery-white, lustrous, relatively soft metal which is unaffected by air or water, even at red heat. Rare and fragile element. Nuclear reactions in stars destroy it. Most and possibly all beryllium originated when cosmic rays smashed into heavier atoms in space and split them into lighter ones, such as beryllium. | Be | |||||||
