Metal objects have high reflectivity and magnetivity. What else do we know about metals? Find out in this fun video. [4:26]

Properties of metals and how we can explain their properties using the electron 'sea' model. [9:28]

Paul Andersen explains how metallic solids form when delocalized electrons hold the positive nuclei in an electron sea. This model helps to explain the properties of metals like conductivity, shiny appearance, malleability, ductility,...
