Americium is an artificial element (only extremely traces exist naturally on the earth); it is obtained by nuclear reactions (from uranium or plutonium) and a very long and difficult process of separation.
Americium can be obtained as a pure element (more exactly isotope).
Yes, americium is a chemical element.
No you cannot make a pure sample of Fluorine because it is an earth made element.
Americium as pure metallic element.
boobies
The half life of americium 241 is 432,2 years.
i actually have no idea what im anwsering............help
The hardness of americium is not typically measured or reported, as it is not a material that is commonly used in its pure form. Americium is a radioactive metallic element that is primarily used in smoke detectors and other specialized applications due to its radioactive properties.
To make a pure sample of iodine, you can start with a mixture containing iodine and other substances, then use a process like sublimation to separate the iodine from the other components. Sublimation involves heating the mixture to allow the iodine to vaporize and then cooling it to condense the iodine back into solid form. This process helps to obtain a pure sample of iodine.
Americium is extracted from spent nuclear fuels where is formed by nuclear reactions.
The sample could be described as pure gold or 100% pure gold.
For example to establish a zero point for an instrument or to make a measurement on water considered as a pure sample.
