Electronic configuration shows placement of electrons in an orbit. Let us study facts about electronic configuration of lawrencium.
The electronic configuration of Lawrencium is [Rn] 5f14 6d1 7s2. It is an artificially created element with atomic number 103 and an element symbol Lr. It is the last of the actinide series of elements and is located in the 7f orbital.
It is represented as Lr and its electronic configuration will be described by various rules and look its orbital diagram. We will further explore more about it in this article.
How to write lawrencium electron configuration
The Lawrencium atom consists of 103 electrons which are arranged according rules mentioned below-
- Aufbau’s principle– The atomic orbitals are filled in increasing order of energies i.e., 1s<2s<2p<3s<3p<4s<4p<5s<4d<5p<6s<6f<5d.
- Pauli’s exclusion principle– orbital can accommodate a maximum of 2 electrons with opposite spin.
- Hund’s rule– state filling up of degenerate orbitals of the same subshell.
- Therefore, final electronic configuration of Lawrencium is- 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p6 4f14 5d10 6s2 6p6 5f14 6d1 7s2.
