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:

1s²2s²2p⁶3s²3p⁶3d¹⁰4s^{2 3d10}4p⁴.

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

Valence electrons are the electrons which are located in the outermost shell of the atom or molecule. Selenium has 6 electrons in its outermost shell i.e. 2 electrons in s orbit and 4 electrons in the p orbit.
