Meitnerium is an extremely radioactive synthetic element named after Lise Meitner. Let us understand the electron configuration of meitnerium through this article.
Electron configuration of meitnerium is [Rn] 5f14 6d7 7s2. Meitnerium is denoted by symbol “Mt” and its atomic number is 109. 278Mt is the most stable isotope of meitnerium having half-life period of 4.5 seconds. It is a synthetic element and can be created inside a laboratory.
We will understand some important facts about meitnerium like orbital diagram, ground state electron configuration etc., in the article below.
How to write meitnerium electron configuration?
Meitnerium contains 109 electrons and electron configuration of any element can be written by following the set of steps mentioned below:
- According to Aufbau’s principle, electrons must be filled up with the order of increasing energy of orbitals available in an atom.
- Pauli’s exclusion principle depicts that pairing of electrons will take place after each orbital contains at least 1 electron.
- Spins of electrons in a particular orbital will be in accordance with Hund’s rule.
