    Amorphous solid Particles are arranged in a random  manner Sometimes called supercooled liquids

    Melting Point Change of a solid to a liquid by the  addition of heat. Temperature that this happens is the  melting point Amorphous solids have no definite  melting point

    4 types of crystals Ionic – charged particles, reg.  Arranged,high melting pts, brittle, good  insulators Covalent network – large number of  atoms covalently bonded, melt at high  temperatures, nonconductors
