The notion of synthetic , from the Greek word synthetikós, has several uses. The first meaning included in the dictionary of the Royal Spanish Academy (RAE ) refers to that linked to the synthesis .

Synthesis is called compendium of one thing ; to the creation of something from the union of its parts ; and in the chemistry , to the process that allows get 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.

He synthetic rubber , for example, is a polymer of elastic behavior (ie, an elastomer). It is usually used as a replacement for natural rubber, which comes from latex of certain plants. He synthetic grass , on the other hand, imitates natural grass and is used in sports fields.

A synthetic chemical element , in this framework, it 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 .

He technetium It was the first synthetic element discovered. It is important to mention that synthetic elements are always unstable and radioactive . They also have a short half-life.

There are elements that were initially 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 found in the natural environment.
