How Were Metals First Discovered?
The first recorded metals used were those found, in an unreacted state referred to as 'Native Metals'. These metals could be mined and used without the need of more complicated extraction or separation from other metals or nonmetallic atoms. Most metals naturally occur as minerals or compounds, where the metal atom has reacted with other metals or nonmetallic atoms, one of the key steps of the development of Metallurgy as a science, revolves around the extraction of metals from their naturally states.

When was aluminum first used?
Aluminum was discovered in 1824 but it was not until 1886 that an industrial large-scale production method was developed. Prices of aluminum dropped and aluminum became widely used in jewelry, everyday items, eyeglass frames, optical instruments, tableware, and foil in the 1890s and early 20th century. Aluminum's ability to form hard yet light alloys with other metals provided the metal many uses at the time. During World War I, major governments demanded large shipments of aluminum for light strong airframes. The most common metal in use for electric power transmission today is aluminum-conductor steel-reinforced. Also seeing much use is all-aluminum-alloy conductor. Aluminum is used because it has about half the weight of a comparable resistance copper cable (though larger diameter due to lower specific conductivity ), as well as being cheaper. Copper was more popular in the past and is still in use, especially at lower voltages and for grounding.
How are metals extracted from the Earth?
Metals are often extracted from the Earth by means of mining ores that are rich sources of the requisite elements, such as bauxite. Ore is located by prospecting techniques, followed by the exploration and examination of deposits. Mineral sources are generally divided into surface mines, which are mined by excavation using heavy equipment, and subsurface mines. In some cases, the sale price of the metal/s involved make it economically feasible to mine lower concentration sources.
What are the elements that are considered metals?
The remaining elements are either metalloids (B, Si, Ge, As, Sb, and Te being commonly recognised as such) or nonmetals. Astatine (At) is usually classified as either a nonmetal or a metalloid, but some predictions expect it to be a metal; as such, it has been left blank due to the inconclusive state of the experimental knowledge. The other elements shown as having unknown properties are likely to be metals, but there is some doubt for copernicium (Cn) and oganesson (Og).
Why are metals useful?
Some metals and metal alloys possess high structural strength per unit mass, making them useful materials for carrying large loads or resisting impact damage. Metal alloys can be engineered to have high resistance to shear, torque and deformation. However the same metal can also be vulnerable to fatigue damage through repeated use or from sudden stress failure when a load capacity is exceeded. The strength and resilience of metals has led to their frequent use in high-rise building and bridge construction, as well as most vehicles, many appliances, tools, pipes, and railroad tracks.
How do metals form solids?
The solid or liquid state of metals largely originates in the capacity of the metal atoms involved to readily lose their outer shell electrons. Broadly, the forces holding an individual atom's outer shell electrons in place are weaker than the attractive forces on the same electrons arising from interactions between the atoms in the solid or liquid metal. The electrons involved become delocalised and the atomic structure of a metal can effectively be visualised as a collection of atoms embedded in a cloud of relatively mobile electrons. This type of interaction is called a metallic bond. The strength of metallic bonds for different elemental metals reaches a maximum around the center of the transition metal series, as these elements have large numbers of delocalized electrons.
How does temperature affect metals?
A temperature change may affect the movement or displacement of structural defects in the metal such as grain bo undaries, point vacancies, line and screw dislocations, stacking faults and twins in both crystalline and non-crystalline metals. Internal slip, creep, and metal fatigue may ensue.
