The electron configuration of selenium refers to the arrangement of electrons in the selenium atom’s orbitals. It describes how electrons are distributed among the various atomic orbitals and energy levels, and provides a detailed map of where each electron is likely to be found.
What is the Electron Configuration of Selenium? The electronic configuration of selenium is represented as 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 4 or [Ar] 3d 10 4s 2 4p 4. Selenium Valence Electrons. Valence electrons are the electrons which are located in the outermost shell of the atom or molecule.
Selenium is a chemical element; it has the symbol Se and atomic number 34. It has various physical appearances, including a brick-red powder, a vitreous black solid, and a grey metallic-looking form. It seldom occurs in this elemental state or as pure ore compounds in Earth's crust.
Selenium is a chemical element with symbol Se and atomic number 34. Classified as a nonmetal, Selenium is a solid at room temperature.
Electron configuration The arrangements of electrons above the last (closed shell) noble gas. Melting point The temperature at which the solid–liquid phase change occurs. Boiling point The temperature at which the liquid–gas phase change occurs. Sublimation
Selenium is a chemical element of the periodic table with chemical symbol Se and atomic number 34 with an atomic weight of 78.9718 u and is classed as nonmetal and is part of group 16 (oxygen group). Selenium is solid at room temperature.
Selenium has thirty-four protons and forty-six neutrons in its nucleus, and thirty-four electrons in four shells. It is located in group sixteen, period four and block p of the periodic table. Metalloid element, belongs to group 16 of the periodic table.
The Electron Configuration of the Selenium is 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁴. You can also show the electronic configuration of the elements with the other elements. So, here we will show you the electronic configuration of Selenium with the help of Argon (Ar).
The electron configuration of Selenium is written as 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p4. In this configuration: 1s2 means 2 electrons in the first shell. 2s2 2p6 means 8 electrons in the second shell.
The electron configuration of selenium is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p4, which can also be represented with arrows in an orbital diagram.
