Selenium Electron Configuration: Selenium (Se) is a fascinating non-metal with atomic number 34, located in Group 16 (the oxygen family) of the periodic table. It sits between sulfur (S) and tellurium (Te), giving it a unique combination of physical and chemical properties. Selenium also shares several characteristics with arsenic, making it an important element in chemistry, electronics, glass manufacturing, and human nutrition. Understanding selenium’s position in the periodic table helps explain its behavior, bonding patterns, and practical uses.

Selenium Electron Configuration
The electronic configuration is defined as the distribution of a number of electrons in the atom or molecule.
Electron Configuration For Selenium
Selenium consists of 34 electrons distribution in its 4 orbits. So electronic configuration of selenium define as:
1s22s22p63s23p63d104s2 3d104p4.
Or
The electronic configuration can also be represented with the help of a full electron distribution element that is Argon/ Ar. In this case it is written as [Ar] 3d104s24p4
What is the Electron Configuration of Selenium?
The electronic configuration of selenium is represented as 1s22s22p63s23p63d104s24p4 or [Ar] 3d104s24p4
Selenium Valence Electrons
The valence electrons of selenium are 6, which means it has six electrons in its outermost energy level. Its outer electron configuration is 4s² 4p⁴, consisting of 2 electrons in the s orbital and 4 electrons in the p orbital. These six valence electrons enable selenium to form a wide range of chemical bonds and compounds, commonly exhibiting oxidation states of −2, +4, and +6. Knowing the selenium valence electrons is essential for understanding its Lewis dot structure, electron configuration, chemical reactivity, and bonding behavior.
