What is the chemical?

In its most basic form, the chemical is an element in that it has a specific molecular composition and can be produced or used during a natural chemical process. An element is a chemical made of specific types of atoms that cannot be divided further; In short, the elements are the cleanest forms of chemicals that are known to humans. When multiple chemicals are combined, a chemical compound that exists to combine different types of elements and therefore different reactions is created.

Purpose

Perhaps the main use of chemicals is to support and increase higher quality of life not only for human race, but also countless other species, as they allow the creation of modern inventions. Everything that consists of matter or anything that is considered solid, liquid or gas consists of chemicals; This means that almost everything you use throughout the day consists of chemicals. Chemicals are used as the basic functions of everyday life; onizn combined by creating manyHo commonly used substances - from water one drink to gasoline, which provides the car its energy.

Just 100 years ago, many of the chemicals used today did not exist, at least not in a familiar form. This includes the chemicals needed to produce things such as modern medicines and cleaning needs. In addition to chemicals that are already used in the modern world, more chemicals are formed every day.

a combination of chemicals

In order to form chemical compounds, it is first necessary to come up with a chemical formula. This formula is only a list of atoms that include atoms types and the number of specific atoms needed to create a substance molecule. This is usually achieved by an atom -type list, followed by the number of atoms needed for this particular.

For example, consider one of the most common chemical patterns known to the world H _{2 O. These are two atomshydrogen combined with one oxygen atom. The result is one of the most basic, the life of maintaining chemicals of known humanity.}

The order of the elements in the formula is usually determined by a hilly system, which states that all carbon atoms will be given first, hydrogen atoms of a second, then all other atoms alphabetically. The exception of this is the ion compounds that will always first mention the positive ion. This is the case of NaCl, a formula for salt.

side effects

However, although chemicals can be a good thing, certain types of chemicals may also have negative effects on both people and the environment. For example, some chemicals may pose serious risks, if they are used, some chemicals are assumed to cause cancer and are known that some chemicals are dangerous to the atmosphere. Many websites and books are devoted to public education about potentially harmful side effects that can be based on chemicals.

chemists orAbout those who work with chemicals are accused of understanding how different chemicals will react to each other. Without this knowledge, it is very possible that experimenting with certain chemicals can lead to catastrophic results.

Chemistry

The study of chemicals is called chemistry. The most basic forms of chemical classes often start in high school and then continue with college institutions. Those who need chemistry background include doctors, pharmaceutical scientists and even food developers and synthetic foods.
