Bohrium Cube Element Mini Museum Praseodymium's atomic number is 59Bohrium's atomic number is 107 and its symbol is Bh. As a synthetic element, it can be created in a laboratory but is not found in nature. All known isotopes of bohrium are extremely radioactive; the most stable known isotope is 270Bh with a half life of approximately 61 seconds. It is named after Danish physicist Niels Bohr. Very few properties of bohrium or its compounds have been measured; this is due to its extremely limited and expensive
