Defining the Covalent Bond: concept walkthrough

Section role: supports the formalization of covalent bonding in Section 3 while the teacher explains theory and introduces polarity. Slides: (1) Title — 'Defining the Covalent Bond: Sharing is Caring'; (2) Etymology and Definition — bullets: co- (together) and valent (valence electrons), visual definition of single, double, and triple bonds using Lewis notation for H2, O2, and N2; (3) The Tug-of-War Analogy — graphic of identical twins pulling equally for nonpolar bonds; (4) Polar Covalent Bonds — graphic of a giant versus a toddler illustrating unequal electron pull and partial charges; (5) Electronegativity Scale — key values and how they predict bond polarity; (6) Ionic vs. Covalent Comparison Chart — transfer versus sharing of valence electrons; (7) Video Integration Prompt — visual cue for the embedded video contrasting bond types; (8) Closing slide — 'How does electronegativity decide the winner of the electron tug-of-war?' — handing control back to the teacher for the mastery check in Section 4.
