Metals are shiny, malleable, ductile, and good conductors of heat and electricity. Is there a reason, chemically, for these characteristics of metal? In this video we explain the connection between the nature of metallic bonds and these typical features. ⬣⬣⬣ LESSON CHAPTERS: 0:00 Characteristics of Metals 0:23 The "Sea of Electrons" model of metals 1:23 Metals are shiny 1:48 Metals are good conductors of heat 2:04 Metals are good conductors of electricity 2:20 Metals are malleable 3:01 Metals are ductile 3:43 Metals have recognizable crystal structures 3:53 Which metal is liquid at room temperature? Any others? Correction: 1:33 This is a description of light emission, not reflection. Reflection is a better explanation for the shininess of metals.

She continued her studies in Molecular Biology (focusing on Immunology and Neurobiology) at Princeton University, where she began teaching as a graduate student. Her success in teaching convinced her to leave the glamorous world of biology research and turn to teaching full-time, accepting a position at an exclusive prep school, where she taught biology and chemistry for eight years. Kimberly co-founded Socratica Studios. ⬣⬣⬣ Creative Commons Picture Credits: sodium chloride 3D lattice http://en.wikipedia.org/wiki/File:NaC...
