|
Answer» Low melting point and boiling pointNon sonorus Low melting , boiling points Non sonorous Physical properties of non-metals\tNon-metals may be either solids, liquids or gases.\tSolid non-metals are brittle and break down into powdery mass on striking with a hammer except diamond which is the hardest non-metal.\tThey have a dull luster but iodine is lustorous.\tThey have low melting points except diamond that has very high melting point.\tThey are poor conductors of heat and electricity except graphite.\tThey are not malleable.\tThey are not ductile.\tThey are not sonorous.\tExamples are carbon, Sulphur, oxygen, phosphorous and many more. Non malleable , non ductile, low tensile strength , poor conductivity, brittle, no metallic lustre |
