This video tutorial explains the differences between ionic and covalent compounds, focusing on how they form and the role of electronegativity. Ionic compounds form between metals and nonmetals, transferring electrons due to significant electronegativity differences. Covalent compounds form between nonmetals, sharing electrons because of similar electronegativity. The video emphasizes the octet rule and how elements achieve stability through electron transfer or sharing.
