What is the Meaning of Metals | Definition and What is Metals

Meanings, definitions, concepts of daily use

Metals are chemical elements able to conduct electricity and heat, which present a characteristic brightness and that, with the exception of mercury, are solid at normal temperature.
The concept is used to designate pure elements or alloys having metallic characteristics. Among the differences with non-metals, there is mention that metals have low energy of ionization and a low electronegativity.
Metals are persistent (they can be sudden forces without to break/break), ductile (might make the wires or cables), malleable (they become leaves/blades when they are compressed) and have good resistance mechanical (resist the efforts of traction, bending, torsion and compression without warping).
There are metals which appear in the form of primary elements (copper, gold, silver), while others can be obtained from oxides, sulfides, carbonates and phosphates. Metals are often used in industry because they offer great stability and have a great protection against corrosion.
The benefits of metals are known by man since prehistory. Initially, used those who were easy to find in the pure State, but others have started to be used gradually (those that were obtained from the use of ovens).
The use of copper ore with Tin helped create the alloy known as bronze, which gave birth to a new historical era (the bronze age).
Today, we can distinguish between the different types of metals, including precious metals (those found in its natural state without the need to combine with others to form compounds) and heavy metals (those that have a high density and have some toxicity).
