Noble Gases: Properties of Each Element

The word neon comes from the Greek word "νέον" and means a new word. Neon lamps are used for glow lamps, high-voltage discharge tubes and billboards, as well as several plasma tubes and refrigerant applications. When used in these products, the neon glows in red and orange. When used with a HeNe laser, neon light also emits this color. With the exception of some commercial uses, hydrazine is not used, one of which is liquid air sorting. Radon is produced by the fusion of oxygen and oxygen in the alpha process.

The chemical nature of the elements, and importantly, their reactivity depends on the number of electrons in the shell. The inert gas has a fully filled valence electron shell, which is a very stable arrangement, so they are inert. Only a few hundred compounds are made from inert gas. A typical experiment attracting students' chemistry is an experiment involving color change. The presenter blends the two colorless liquids whose colors change "miraculously" or appear as colored deposits. This is one of the most obvious examples of chemical reaction - but it depends entirely on physics, atomic structure and electron placement.

The classic "turret and turret" periodic table shows the characteristics of elements and how they interact. Elements contained in each column share properties such as metals and inert gases. The arrangement also shows the electronic configuration, size, weight, and electronegativity of the element. In the 21st century it is difficult to truly grasp the desperation of escape from infectious diseases. But even doctors in the past do not understand how this disease spreads and how to prevent it. In the 19th century, even scientists generally believed that diseases such as cholera and typhoid were caused by "bad air".

The name "nobility" comes from the fact that it seems that all of these gases are separated from other elements and that they seldom interact with them to form compounds. Therefore, some chemists believe that noble gases do not even belong to the periodic table. Mendeleev and someone else did not anticipate these elements, and for the first time after six years of effort, chemists and physicists can successfully incorporate noble gases into the table. In a new configuration, an additional column is introduced between the halogens (gaseous elements fluorine, chlorine, bromine, iodine and ast) and alkali metals (lithium, sodium, potassium, rubidium, cesium and furan).
