Dubnium Electron Configuration:7 Facts You Should Know!

Dubnium belongs to group 5 and period 7 of theperiodic table. Let us see the electronic configuration of Dubnium.

The electronic configuration of Dubnium is [Rn] 5f14 6d3 7s2. Dubnium (Db) is a transuranium element; it is a highly radioactive metal. The atomic number of Dubnium is 105, a super heavy element. It synthesize artificially; it does not occur naturally on earth. It had a Body-centered cubic crystal structure.

We will discuss some facts about Dubnium electronic configuration in this article, such as writing Dubnium electronic configuration, as well as the orbital diagram of Db.

How to write dubnium electron configuration

The Dubnium atom has 105 electrons.

The step-by-step approach to writing electron configuration is given below:

  • In the Fundamental step, we write the shell number.
  • For Dubnium, there was a total of 7 shell numbers, so we wrote in the fundamental step.
  • In this Second step, we indicated the orbitals.
  • There are four orbitals in which the electrons are filled in an atom s, p, d, and f.
  • s orbitals have a maximum capacity of holding 2 electrons, and p, d, and f have a capacity of holding 6, 10, and 14 electrons, respectively.
  • The orbitals are written in this following 1s 2s 2p 3s 3p 3d 4s 4p 4d 4f 5s….
  • In the third step put the subscripts for writing electron configuration in the final step.
  • Finally, the number of electrons is put in the orbitals as per their highest capacity of holding the electrons in their orbitals, in the form of subscripts.

 So, the final configuration is
