Concept of Valence Electrons
What are valence electrons?
Imagine an atom as a miniature solar system with the nucleus as the sun and the electrons orbiting it like planets. Valence electrons are the electrons that reside in the outermost orbit, or energy level, of an atom. They are the most energetic and reactive electrons, and they play a crucial role in determining an element’s chemical properties.
Selenium’s electron configuration and valence electrons
Selenium is a chemical element with the symbol Se and atomic number 34. Its electron configuration is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁴. This means that selenium has 4 valence electrons in its outermost 4p orbital.
Significance of valence electrons
Valence electrons are essential for chemical bonding, the process by which atoms join together to form molecules. They are responsible for the chemical reactivity of an element because they can easily be gained, lost, or shared to form chemical bonds with other atoms. In the case of selenium, its 4 valence electrons allow it to form covalent bonds, which are bonds formed by the sharing of electrons between atoms.
Atomic Orbitals and Valence Electrons
Imagine Selenium atoms as tiny celestial bodies with a bustling atmosphere of valence electrons. These electrons occupy specific regions known as atomic orbitals, akin to cozy apartments in a celestial metropolis.
Selenium’s four valence electrons reside in its 4p orbitals, designated as px, py, and pz. These orbitals are shaped like elongated balloons, with the px and py orbitals lying in a plane and the pz orbital pointing along the z-axis.
Each atomic orbital can accommodate a maximum of two electrons, so Selenium’s four valence electrons fill two of these orbitals, leaving two others unoccupied. This arrangement is akin to two families inhabiting adjacent apartments, each with two children occupying their respective bedrooms.
