Metals are materials that are good conductors of electricity and heat. Metals make up a majority of the elements on the periodic table, and are classified as either base or precious. Base metals are more commonly occurring than precious and are used in nearly every aspect of modern life. They are an invaluable component of electrical engineering. Industries as widely varied as transportation, construction, farming, communications, and medicine rely on metals.
- Alkali metals - the metals that compose the group 1 elements in the periodic table
- Alkaline earth metals - the metals that compose the group 2 elements of the periodic table
- Alloys - the mixture or solid solution of two or more elements
- Aluminum - a silvery white metal of the boron group of elements, with the symbol Ai and the atomic number 13
- Heavy metals
- Metalloids - elements that cannot be easily classified as a metal or nonmetal, including semiconductors such as silicon
- Molten metal and solidification
- Precious metals
- Transition metals - an element whose atom has an incomplete d sub-shell, or, commonly, any element in the d-block of the periodic table
