Is samarium a solid?
What are samarium physical properties?
Samarium is a yellowish metal with a melting point of 1,072°C (1,962°F) and a boiling point of about 1,900°C (3,450°F). Its density is 7.53 grams per cubic centimeter. Samarium is the hardest and most brittle of the rare earth elements.
What is samarium chemical properties?
Samarium is a silvery-white metal belonging to the lanthanide group of the periodic table. It is relatively stable at room temperature in dry air, but it ignites when heated above 150 C and forms an oxide coating in moist air. Like europium samarium has a relatively stable oxidation state (II).
Does samarium react with water?
Reaction of samarium with water
The silvery white metal samarium is quite electropositive and reacts slowly with cold water and quite quickly with hot water to form samarium hydroxide, Sm(OH)3, and hydrogen gas (H2).
What are samarium uses?
Samarium is used to dope calcium chloride crystals for use in optical lasers. It is also used in infrared absorbing glass and as a neutron absorber in nuclear reactors. Samarium oxide finds specialised use in glass and ceramics.
Does the human body use samarium?
According to researchers, samarium speeds up metabolism. In the human body, the metal is found in the bloodstream, kidneys, and liver. Exposure may cause eye and skin irritation because the salts and compounds are found to be moderately to highly toxic. The metal has been found in some plants and animals as well.
How much is samarium worth per gram?
Samarium costs about $5 per gram, around a third of the price of gold. Samarium's primary use is in samarium cobalt alloy magnets, which are particularly powerful; these are used in consumer applications such as headphones as well as in industrial contexts.
What is an interesting fact about samarium?
Interesting Facts about Samarium
Paul-Émile Lecoq de Boisbaudran also discovered gallium, gadolinium and dysprosium.
Is samarium cobalt toxic?
DANGER FOR CHILDREN
If more than one magnet is swallowed, they can get stuck and pinch the digestive tract causing major swelling and even life-threatening injuries requiring surgery. Larger magnets can crush fingers and break bones. Always keep Samarium Cobalt magnets out of the reach of children.
Is samarium a transition metal?
Samarium is one of the rare earth elements found in Row 6 of the periodic table. ... It is named after the element lanthanum, a transition metal also often considered a lanthanide. Samarium looks and behaves like most other metals, but it has relatively few uses.
What is the average concentration of samarium?
- With the average concentration of about 8 parts per million (ppm), samarium is the 40th most abundant element in the Earth's crust. It is the fifth most abundant lanthanide and is more common than elements such as tin.
What is samarium atom?
- Samarium atom is a lanthanoid atom and a f-block element atom. Samarium has been used in trials studying the treatment and prevention of Pain, Cancer, Metastasis, Prostate Cancer, and Metastatic Osteosarcoma, among others.

What is Samarium oxide?
- Samarium is an element of the rare earth family of metals. It has the atomic symbol Sm, atomic number 62, and atomic weight 150.36. The oxide is used in the control rods of some nuclear reactors.
What is the difference between samarium 153 and samarium 149?
- The radioactive isotope samarium-153 is the active component of the drug samarium ( 153 Sm) lexidronam (Quadramet), which kills cancer cells in the treatment of lung cancer, prostate cancer, breast cancer and osteosarcoma. Another isotope, samarium-149, is a strong neutron absorber and is therefore added to the control rods of nuclear reactors.
What are the physical properties of samarium?What are the physical properties of samarium?
