Learn how the periodic table organizes elements by atomic number and reveals fundamental patterns in their physical and chemical properties in this 12-minute chemistry video. Discover how elements are systematically categorized as metals, nonmetals, or metalloids based on their distinct behaviors and characteristics. Explore how vertical groups in the periodic table share similar chemical properties due to their identical number of valence electrons. Understand the octet rule and how it explains atomic stability through the gaining, losing, or sharing of electrons to achieve complete outer electron shells.
