Hafnium, the mysterious element of the periodic table

Scientists all over the world knew that hafnium existed. But they did not know what it was, how it looked, nor did it have a name. Then one day, in the year of 1923, Dirk Coster and George Charles von Hevesey, famous chemists, finally discovered this wondrous element, which was the missing one in the periodic table. Element number 72. The scientists used a method called X-ray diffraction analysis and struck upon this element as a part of a Norwegian zircon. Since this discovery was made in Copenhagen, Denmark, the scientists decided to honor the city by naming the element Hafnium, which is derived from the Latin name of Copenhagen-Hafnia.
