Covalent Bonding: Sharing Electrons to Form Stable Molecules

This video discusses covalent bonding in chemistry. The presenter starts by explaining that atoms or elements want to have a full outer shell of electrons for stability. They then use examples of how non-metals like fluorine and oxygen react to form covalent bonds by sharing electrons. The video covers various types of covalent bonds like single, double, and triple bonds and explains how they can be represented using different molecular formulas and models like the dot and cross diagram, structural formula, and 3D models. The presenter also discusses valency and its use in determining simple molecular formulas. The video concludes with an example of finding the molecular formula of carbon sulfide.
