What is Metal?
Some [[chemical element]]s are called '''metals'''. Most elements in the [[periodic table]] are metals. These elements usually have the following traits: # They can conduct electricity and heat.<ref>{{Cite web|last=Metals|first=Non Metals|date=2021-09-24|title=Metals and Non Metals|url=https://alljobs.co.in/study-material/metals-and-non-metals-class-10/|access-date=2021-12-06|language=en-US|archive-date=2023-01-08|archive-url=https://web.archive.org/web/20230108141825/https://alljobs.co.in/study-material/metals-and-non-metals-class-10/|url-status=dead}}</ref> # They can be shaped easily. # They have a shiny appearance. # They have a high melting point. Most metals are solid at room temperature, but this does not have to be the case. [[Mercury (element)|Mercury]] is liquid. [[Alloy]]s are mixtures, where at least one part of the mixture is a metal. Examples of metals are [[aluminium]], [[copper]], [[iron]], [[tin]], [[gold]], [[lead]], [[silver]], [[titanium]], [[uranium]], and [[zinc]]. Well-known alloys include [[bronze]] and [[steel]]. The [[Research|study]] of metals is called [[metallurgy]]. == The ways that metals are alike (properties of metals) == Most metals are hard, shiny, they feel heavy and they [[melt]] only when they are heated at very high temperatures . Lumps of metal will make a bell-like sound when they are hit with something heavy (they are sonorous). [[Heat]] and [[electricity]] can easily pass through a metal (it is [[electrical conductivity|conductive]]). A lump of metal can be beaten into a thin sheet (it is [[malleability|malleable]]) or can be pulled into thin wires (it is [[ductility|ductile]]). Metal is hard to pull apart (it has a high [[tensile strength]]) or smash (it has a high [[compressive strength]]). If you push on a long, thin piece of metal, it will bend, not break (it is [[elasticity (physics)|elastic]]). Except for cesium, copper, and gold, metals have a neutral, silvery color. Not all metals have these properties. Mercury, for instance, is liquid at room temperature, [[L
