Is promethium malleable?
Yes. Promethium is a rare earth metal and is found in the periodic table in the Lanthanide section. Its symbol is Pm and it has the atomic number 61. It was predicted to exist, but could not be found in the earth's crust. Promethium has no stable isotopes, and what ones it has are relatively short-lived. It was first isolated from spent nuclear fuel, and later discovered in ores of uranium, but only in the most minute quantities.
How many additional radioactive element discovered since Marie Curie discovered radium and polonium?
All chemical elements after uranium and promethium, technetium.
