Why is Copernicium in Period 7?

Why is Copernicium in Period 7

Let me ask you a question.

How many shells does a copernicium atom have?

It’s 7. Right? 

You have already seen the bohr model of copernicium atom in the above table.

From the Bohr model, it can be found that the number of orbits or shells in copernicium is 7. Hence, as copernicium has 7 orbits, it lies in period 7 of the Periodic table.

Why is Copernicium in d-block?

Why is Copernicium in d-block

Before knowing this reason, first of all I want to ask you a simple question.

How can you determine the blocks-wise position of elements?

The simple answer: The elements will lie in the s, p, d or f block will completely depend upon the subshell in which the last electron will enter.

For example; the electron configuration of copernicium is [Rn] 5f14 6d10 7s2

So the last electron of copernicium enters the d-subshell or d-orbital. 

Hence, copernicium is the d-block element.

5 facts about Copernicium

Interesting facts about copernicium element are mentioned below.

  1. The element was given the name “Copernicium” to honor the scientist Nicolaus Copernicus.
  2. Copernicium was discovered by Sigurd Hofmann and his colleagues in 1996.
  3. Copernicium is not available naturally and it is artificially prepared in a laboratory.
  4. There are 7 known isotopes of copernicium and all those isotopes are radioactive in nature.
  5. The most stable isotope of copernicium is 285Cn, which has a half life of 28 seconds.

Properties of Copernicium

The physical and chemical properties of copernicium element are mentioned below.

  • The copernicium element is extremely radioactive and has a very short half life.
  • The calculated atomic mass of the most stable isotope of copernicium is 285 u and its calculated density is 14 g/cm3.
  • The copernicium is predicted to have liquid phase at STP.
