What is the luster of curium?
Curium is similar in some regards to gadolinium, its rare earth homolog, but it has a more complex crystal structure. Curium metal is lustrous, malleable, silver in color, chemically reactive, and is more electropositive than aluminum.
What is the texture of curium?
Curium is a hard, brittle, silvery radioactive metal that tarnishes slowly and which can only be produced in nuclear reactors. The isotope 242Cu was produced in 1944 by Glenn T Seaborg, Ralph A James and Albert Ghioso by bombarding 239Pu with alpha particles in the 60-inch Cyclotron at Berkeley University in the US.
What is unique about curium?
Curium is a hard, dense radioactive silvery-white metal. It tarnishes slowly in dry air at room temperature. Most compounds of trivalent curium are slightly yellow in color. Curium is highly radioactive and it glows red in the dark.
Is Curium a solid?
Curium is a chemical element with symbol Cm and atomic number 96. Classified as an actinide, Curium is a solid at room temperature.
Where is curium on the periodic table?
curium (Cm), synthetic chemical element of the actinoid series of the periodic table, atomic number 96.
Is Curium a solid liquid or gas?
This element is a solid. Curium classified as an element in the Actinide series as one of the “Rare Earth Elements” which can located in Group 3 elements of the Periodic Table and in the 6th and 7th periods.

Is curium a synthetic element?
curium (Cm), synthetic chemical element of the actinoid series of the periodic table, atomic number 96. Unknown in nature, curium (as the isotope curium-242) was discovered (summer 1944) at the University of Chicago by American chemists Glenn T. Seaborg, Ralph A.
