Hi everyone! I haven’t published videos about chemical elements for a long time. Today I would like to tell you about the most recently discovered non-radioactive metal, that is about hafnium. If to look at the periodic table, you will see that hafnium is located at the bottom of group 4 along with zirconium and titanium. It is there not accidentally, because all these three metals share common chemical properties especially zirconium and hafnium. That is the reason why hafnium is usually found combined with zirconium in rocks for instance in such minerals as zircon where hafnium concentration ranges from 1 to 4%. The striking resemblance of this element with an atomic number 72 to zirconium, was the very reason why it was discovered only in 1923 in Copenhagen. It was named after Latin name of the Danish capital - Hafnia. Here you can see the reagents and also obtained metallic hafnium which George de Hevesy, the discoverer of the element, used in his experiments.
