The Composition of Rocks: Mineral Crystallinity and Bonding Types

The video tutorial explores the basics of rocks and minerals, focusing on their definitions, properties, and classifications. It discusses the criteria for defining minerals, including crystallinity and chemical composition, and explains the types of chemical bonds found in minerals, such as covalent, ionic, and metallic bonds. The tutorial also covers the bonding spectrum and concludes with a summary of mineral properties.
