Who discovered promethium?
It was Jacob A. Marinsky, Lawrence E. Glendenin and Charles D. Coryell who discovered promethium. It had been predicted many years before, but had never been found or isolated. A link can be found below for more information.
What is the particle emitted when neodymium-144 decays into promethium-144?
When neodymium-144 decays into promethium-144, it emits a beta particle. This process involves the transformation of a neutron into a proton within the neodymium nucleus, resulting in the emission of an electron (the beta particle) and an antineutrino. The increase in the proton number by one changes the element from neodymium to promethium while the atomic mass remains essentially the same.

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.
