A non-conductor is a solid that do not allow electric current to pass through.Īll metals conduct electricity.

Non-metals are dull, not ductile (do not form wires), not malleable (do not form sheet) and break on coiling/brittle. Metals are shiny, ductile(able to form wires), malleable(able to form sheet) and coil without breaking. iv) Skimming-this involve scooping floating particles.Iii) Filtration-this involves sieving /passing particles of a mixture through a filter containing small holes that allow smaller particle to pass through but do not allow bigger particle to pass through. ii) Decantation-this involve pouring out a liquid from a solid that has settled /sinking solid in it.i) Sorting/picking-this involve physically picking one pure substance from a mixture with another/other. ![]() Simple methods of separating mixtures at basic chemistry level include: Search for:Ī mixture is a combination of two or more substances that can be separated by physical means.
