How do you make a pure sample of Iodine?
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.
Which country is fluorine discovered?
Fluorine was prepared as a pure element for the first time in France by Moissan in 1886.
What type of bond is formed when fluorine and fluorine are combined?

What can absorb fluorine?
Materials such as calcium, alumina, and barium can absorb fluorine due to their ability to form strong chemical bonds with the fluorine atoms. Additionally, activated carbon and certain metals like iron and nickel can also absorb fluorine effectively.
Is F2 a compound or a pure substance?
F2 (fluorine) is an element and thus a pure substance. However a compound is a pure substance as well.
A sample is composed completely of gold absolutely free of impurities Which term or terms could be used to describe this sample?
