Properties and Conductivity of Metals

This video tutorial introduces students to the physical properties of materials, focusing on metals, non-metals, and metalloids. It covers key concepts such as luster, malleability, conductivity, and ductility, providing examples and explanations for each. The video also offers practical applications and encourages students to review additional resources available on Google Classroom and Quizlet.
