After which Danish city is the 72th element on the periodic table named?

  • Skagen
  • Odense
  • Herning
  • Copenhagen
Explanation

The 72nd element on the periodic table is named Hafnium, which is derived from the Latin name for Copenhagen, "Hafnia." This is because Hafnium was discovered by Danish chemist Dirk Coster and his American partner George Charles de Hevesy in 1923 while they were conducting research at the University of Copenhagen. As a tribute to the city's significant role in the element's discovery, they decided to name it after Copenhagen. Hence, Copenhagen is the Danish city after which the 72nd element on the periodic table is named.
