What is Samarium? ;
Samarium is a rare earth metal that is typically silver in color. It is a brittle metal that is relatively stable in air and water. Samarium has a number of applications, including use in magnets, lasers, and fluorescent lights.
Uses Of Samarium
Samarium oxide is used in the production of magnets, specifically high-strength magnets. Samarium oxide is also used in the production of ceramics.
Properties Of Samarium
Samarium is a lanthanide element with the symbol Sm and atomic number 62. It is a soft, silver-white metal that tarnishes in air. Samarium is stable in dry air but reacts with water to form the hydroxide, which is poisonous. Samarium is a good conductor of electricity.
Physical Properties Of Samarium
Samarium is a silver-white metal that is relatively soft and has a low melting point. It is also relatively rare, occurring in nature as a component of the mineral samarskite. Samarium is a good conductor of heat and electricity and is corrosion-resistant. It is also non-toxic.

Samarium is a member of the lanthanide series of elements. It is a silver-white metal that is soft enough to be cut with a knife. Samarium is not found free in nature but is found in minerals such as monazite and bastnasite. Samarium has a hexagonal crystal structure and is a good conductor of heat and electricity. It is used in magnets, lasers, and nuclear reactors.
Compounds Of Samarium
Samarium (Sm) is a chemical element with the symbol Sm and atomic number 62. It is a rare earth metal. Samarium is a soft, silver-white, ductile metal. It is found in nature as the mineral samarskite. Samarium is used in magnets, lasers, and atomic clocks.
