Metals are generally lustrous, are able to conduct heat and electricity, have high melting points, are malleable, remain solid at room temperature and appear opaque in thin cross-sections. Non-metals have a dull appearan... More »

Ferrous metals contain iron and non-ferrous metals do not. However, it is not possible to tell which metals have iron in them and which ones do not simply by looking at them unless the person inspecting the items knows a... More »

The major defining feature of metals is that electrons flow relatively freely between atoms in any object composed of two or more metal atoms, whereas electrons around nonmetals are more tightly bound to their respective... More »

In general, metals, unlike nonmetals, are good conductors of heat and electricity, malleable, ductile, and almost always solid at room temperature. Metals very often have only between one and three electrons in their out... More »

Elements that are metals tend to be good conductors of heat and electricity, highly reactive, malleable, ductile, shiny, opaque and solid at room temperature. However, individual metals vary in how well they match this d... More »

Metals have high melting and boiling points compared to non-metals because they are good conductors of heat and electricity, while non-metals are poor conductors of heat and electricity. Metals are solids at room tempera... More »

Most metals are solids at room temperature as they have high melting points. Mercury is the only metal that occurs in liquid form at this temperature. More »
