Copernicium Chemical Classification

  • Copernicium is a highly radioactive metal and only a few atoms have been produced.
  • Cn is classified under the ‘d’ block element.
  • Cn is the heaviest group 12 element পর্যায় সারণীতে।
  • Cn is synthetic chemical element that have been produced in Laboratory.

Copernicium state at room temperature

Copernicium is solid at room temperature which is classified as a transition metal.

Is Copernicium Paramagnetic ?

Elements having incomplete subshells in one of its electron shells are paramagnetic in nature. Let us see if Cn is paramagnetic or not.

Copernicium is not paramagnetic in nature. In Cn, all the subshells are filled with paired electrons in each orbital.


Copernicium is highly radioactive transition metal and has a short half life. Till now very few Cn atoms have been produced. It can be produced in laboratory and is used for research purpose.
