A metal is an element that is solid at room temperature (although mercury is a well-known exception), is shiny and silvery, conducts electricity and heat well, can be pounded into thin sheets (a property called malleability), and can be drawn into thin wires (a property called ductility). Note that chemical changes are frequently accompanied by physical changes, as the new matter will likely have different physical properties from the original matter. As the matter in the match burns, its chemical composition changes, and new forms of matter with new physical properties are created. On the left is some elemental mercury, the only metal that exists as a liquid at room temperature. When a substance goes from one state of matter... Chemistry. This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment.

Assuming that the iron and sulfur are simply mixed together, it should be easy to see what is iron and what is sulfur, so this is a heterogeneous mixture. On the right, elemental sulfur is a yellow nonmetal that usually is found as a powder. 15. It is very brittle and cannot be made into thin sheets or long wires. A physical change occurs when a sample of matter changes one or more of its physical properties. This 4 DVD set contains 19 individual, 20-45 minute segments examining the world of chemistry and the periodic table of the … We can usually divide elements into metals and nonmetals, and each set shares certain (but not always all) properties. Give an example of matter in each phase: solid, liquid, or gas. Basic Chemistry Vocabulary List • absolute temperature: This is a temperature reading made relative to absolute zero. Identify each as a heterogeneous mixture or a homogeneous mixture. Elemental carbon is a black, dull-looking solid that conducts heat and electricity well. Iron is a metal because it is solid, is shiny, and conducts electricity and heat well. Return 9.
