Physical properties like luster, malleability, and ductility help distinguish the 118 building blocks called elements. These elements are grouped into three categories based on shared characteristics: metals, metalloids, and non-metals. The periodic table organizes these groups in repeating patterns, which helps predict how they behave. ----- Sections: 00:00 Intro 00:38 What are elements? 01:47 What are physical properties? 02:17 Luster, malleability, ductility, and fluorescence 04:51 Metals, metalloids, and non-metals 08:25 The periodic table 10:32 Abundant elements 11:26 Summary ----- Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere.
