What is the densest non radioactive element?
The densest of the stable (non-radioactive) elements is the metal osmium, which is twice as dense as lead and weighs almost 22.6 times as much as water.
Which element has highest density?
osmium
As it turns out, either of two elements can be considered the element with the highest density: osmium or iridium. Both osmium and iridium are very dense metals, each weighing approximately twice as much as lead.
Are alloys homogeneous or heterogeneous?
An Alloy is a homogeneous mixture because its composition is uniform.
How do you make an alloy?
It is made up of two or more chemical elements, of which at least one is a metal. An alloy has properties different from the metals it is made of. Most alloys are made by melting the metals, mixing them while they are liquid to form a solution, then leaving them to cool and turn solid again.
What is the heaviest element with at least one isotope that is not radioactive?
The heaviest element that occurs in large quantity is uranium (atomic number 92). You can mine it like gold. Technetium (atomic number 43) does not occur naturally. Promethium (atomic number 61) does not occur naturally.
What do you mean by high density?
having a high concentration: entering a high-density market with a new product; high-density lipoprotein. Computers. (of a disk) having a large capacity for data storage: high-density DVDs.
Are non metals have low density?
Yes, generally non-metals tend to have low density. This is mainly because non-metals tend to exist either in a gaseous or liquid state. Hence, non-metals have low density.
What type of mixtures are alloys?
An alloy is a mixture or metallic-solid solution composed of two or more elements. Examples of alloys include materials such as brass, pewter, phosphor bronze, amalgam, and steel. Complete solid solution alloys give single solid phase microstructure.
What type of mixture is formed by alloys?
homogeneous mixture
Alloys are mixtures of metals or a mixture of a metal and another element. An alloy may be a solid solution of metal elements (a homogeneous mixture) or a mixture of metallic phases (a heterogeneous mixture of two or more solutions).
What is an alloy How is an alloy made?
Alloys are made by mixing two or more elements, at least one of which is a metal. This is usually called the primary metal or the base metal, and the name of this metal may also be the name of the alloy.
What is bismuth trioxide and how is it used?
Bismuth trioxide, on the other hand, is a naturally occurring ceramic material that is widely used in a range of industrial applications such as semiconductor devices, electronic and electro-optical components, magnetic memory, and catalysis.
What is the use of bismuth in latex shields?
Bismuth is used in bismuth-impregnated latex shields to minimize exposure during medical examinations such as x-ray imaging or computed tomography scans. However, it is a brittle material with a tendency to crack.
What are some of the best high density liquids?
Might be fun though. highly water soluble tungstates such as sodium metatungstate have been traditionally used as high-density liquids. you can get above a specific gravity of 3 easily if i recall correctly using this kind of solution. True again, but sodium metatungstate goes for like $800/kilo.
What is the difference between PMMA and PMMA with bismuth trioxide?
Pure PMMA (0\% bismuth trioxide) has HVL of 38 cm, while PMMA with a 44\% loading of bismuth trioxide particles has a HVL of only 5 cm.
