Understanding Covalent Bonds: A Guide to Sharing Electrons in Molecules
Enroll
Covalent bonding is a chemical bond formed when two atoms share one or more pairs of electrons, enabling each to attain the electron configuration of a noble gas and thus achieve greater stability. The strength of a covalent bond is determined by the distance between the nuclei of the bonded atoms and the overlap of their electron orbitals, with greater overlap leading to stronger bonds, as described by molecular orbital theory. The properties of covalent compounds, such as boiling and melting points, electrical conductivity, and solubility, are intrinsically linked to the nature of the covalent bonds and the molecular geometry, which are dictated by the principles of valence shell electron pair repulsion (VSEPR) theory and electronegativity differences between the bonded atoms.
Covalent bonds: the ultimate example of how sharing really is caring at the atomic level, keeping atoms in a stable relationship without the need for a counselor.
Lesson 2
Atoms engage in the ultimate form of chemical camaraderie, sharing electrons in covalent bonds to achieve the enviable stability of the noble gases without the need for a royal title.
Lesson 3
The strength of a relationship between atoms escalates from single to triple covalent bonds, much like the intensity of a handshake evolving from a polite greeting to a bone-crushing grip.
Lesson 4
Polar covalent bonds are the social butterflies of molecular interactions, sharing electrons unequally and creating a world of dynamic chemical personalities, while their nonpolar counterparts prefer a more balanced and equitable electron-sharing relationship.
