The notion of synthetic, from the Greek word synthetikós, it has several uses. The first meaning included in the dictionary of the Royal Spanish Academy (RAE) refers to what is linked to synthesis.
Synthesis is called compendium of one thing; to creating something from the union of its parts; and in the chemistry, to the process that allows obtain a compound starting from substances that are simpler.
The synthetic, therefore, is something that is made from the parts to achieve a whole. The most common use of concept is associated with the product manufactured by industrial mechanisms and techniques that allow to reproduce the characteristics of a natural substance.
The synthetic rubber, for example, it is a polymer with elastic behavior (ie, an elastomer). It is often used as a replacement for natural rubber, which comes from latex of certain plants. The synthetic grass, for its part, it imitates natural grass and is used in sports fields.
A synthetic chemical element, in this framework, does not arise naturally in our planet, but it is developed artificially. There are more than twenty synthetic elements, with atomic numbers ranging from 95 to the 118.
It is important to mention that synthetic elements are always unstable Y radioactive. They also have a short half-life.
The technetium it was the first synthetic element discovered. Within the group of those that do not have stable isotopes, it is the lightest of all. In addition, it is the first that we can find in the periodic table, where we recognize it by its symbol and its atomic number, Tc and 43 respectively.
Before continuing, we must point out that it is a transition metal, that is, they are located in the center of the system periodic and includes the D orbital in its electronic configuration, partly filled with electrons. It is silvery-gray and crystalline in color, and its chemical properties are halfway between those of manganese and rhenium.
There are elements that at first were created artificially and that is why they were mentioned as synthetic elements, although with the passage of weather they were detected in nature. One of them is the plutonium, which was synthesized in 1940 and only later was it found in the natural environment.
In another area, this term is used to give a name to the synthetic sound, a fairly broad concept, since it is used to give a name to any sound that is made through the use of an electronic device with the purpose of imitating that of a instrument real, a group in which we must include the human voice, or that of other living beings.
Synthetic sound is very common today, particularly to complement graphical elements in computer programs and mobile device applications. Let’s think about a basic example: pianos Electronics emit a synthetic sound that mimics that of an acoustic instrument. In fact, many models allow us to “imitate” the sound of more than one instrument, such as the guitar, the violin and even drums and drums, all of them using the typical keys of a piano.
Although we can argue that its qualities cannot compete with those of a natural sound, produced by a real instrument and enriched by the acoustic qualities of its environment, the synthetic one has several advantages. One of them is cost: few people have the money to buy a grand piano, while the price of an electronic keyboard is very affordable. In the cinematographic field, on the other hand, creating the sounds for a film on a computer is much more accessible than method traditional.
