How to write the Orbital Diagram for Selenium?
Selenium (Se) has 34 electrons orbiting its nucleus. These fill shells in layers, with the innermost holding 2 electrons and the second layer squeezing in 8. Deeper shells handle the rest, leaving 6 electrons in the outermost shell that play a crucial role in bonding with other elements. We call these outermost 6 electrons selenium’s valence electrons.
