This chemistry video tutorial provides a basic introduction into solids. It explains how to classify a solid as ionic solids, molecular solids or atomic solids. There are 3 different types of atomic solids that you need to be familiary with - metallic solids, Group 8A solids, and network covalent solids. Ionic solids are typically made up of metals and nonmetals. Ionic solids contain ions with positive and negative charges. Molecular solids are composed of molecules and have very low melting points. Ionic solids typically have high melting points. Metallic solids are composed of metals with varying melting points. Metallic solids conduct heat and electricity very well. They are ductile and malleable. Group 8A solids which are basically the noble gases have extremely low melting points. Finally, the network atomic solids or network covalent solids have a very high melting point which typically varies with pressure.
