He adjective inert , which derives from the Latin word iners, has several uses. It may be that or that has no movement, does not register activity or cannot react .
For example: "The boy remained inert under the bed until the thief left the house", “An inert prosecution does not help victims of crime get justice”, “If the government remains inert to the increase in unemployment, the crisis social will continue advancing ”.
Ine also refers to what it lacks lifetime : “When the police entered the home, he found the inert old man on the ground”, "The inert body of the man remained in the street for several hours", “The hotel owner discovered the young inert in the room”.
In the field of chemistry, this notion serves to define a thing that is not chemically reactive , that is, it cannot provoke or participate in a chemical reaction . This phenomenon is defined as any thermodynamic process in which two or more substances (which are called reagents or reactants) undergo a change in its molecular structure and its links to give rise to a new substance (known as a product). It should be noted that this substance that arises from the chemical reaction has different characteristics and properties than its predecessors.
A Noble gas , on the other hand, it is a substance that, under certain conditions of temperature and Pressure , result non reactive . Precisely because of this supposed lack of reactivity, in the past it was known as inert gas .
This apparent lack of reactivity in inert gases is generated because the electronic layers they are full, making it difficult to lose or acquire electrons . Electronic layers are also known as electron layers and they are defined as the distribution of an orbital with a certain number of electrons that rotate in throne to the nucleus of an atom.
Today, anyway, it is known that these gases can also react and generate compounds Chemicals: For this reason, it is preferred to talk about Noble gases . A clear example is the xenon tetrafluoride.
It should be noted that the decision to qualify as inert to the Noble gases It was not arbitrary at all. Even today it is relatively expensive to get one of these substances to be part of a chemical reaction, since a large volume of Energy to take place (usually in the form of heat, radiation or pressure) and the use of catalysts (substances that serve to accelerate the process of the chemical reaction).
It is also possible to use the word inert in a relative way, as happens when talking about molecular nitrogen : It is said that under normal conditions it is inert and that it exists in the form of diatomic molecules (they are formed by two atoms, of the same chemical element or not). Since in this molecule there is a link Triple covalent very strong, it is not normal to react.
That said, it is possible to generate a chemical reaction between nitrogen gas and lithium to give rise to lithium nitride, even though they are in terms normal.
The pesticides They can be made with ingredients classified into two large groups: inert and active. The inert are those that have no toxic effects on the species that tries to combat the product, although this does not mean that it does not cause any negative consequences on other species or that it is not toxic to people.
A inert ammo Finally, you have your incendiary or explosive material uninstalled or disabled. This means that such ammunition cannot exploit Or cause harm.
