Atoms and Bonding Concepts Explored

This video tutorial explores the intersection of chemistry and biology, focusing on atomic structure, the periodic table, and chemical bonding. It covers the basics of atoms, including protons, neutrons, and electrons, and explains how ions are formed. The tutorial also delves into the periodic table, isotopes, and the formation of compounds through ionic and covalent bonds. Key patterns in the periodic table and exceptions to common rules are highlighted, preparing students for related activities.
