Isotopes of curium have masses between 232 and 252. It is your choice to subtract 1oo from (232 to 252) and to found an isotope. I have the same homework!!! The answer is calcium. - Linz The most important isotope of curium has an atomic weight of 247; 247-100 is 147. This is the mass of an important isotope of promethium.
Cerium was discovered in 1803 Cerium--- Ce atomic number--- 58 atomic mass--- 140.116 # of protons--=58 # of neutrons--- 82 # of electrons---58
We can find Cerium as a non metal element. Atomic number of it is 58.
