Argon and radon are generally classified as nonreactive gases. These gaseous chemical elements are classified as noble gases in the periodic table.Know More
A chemical element is represented in the periodic table by a chemical symbol, an atomic number and atomic mass. Elements are organized in increasing atomic numbers that obey a certain periodic law. Elements that are listed within a row have the same period while those that fall under a column belong to the same group, which is often given a special name.
Different methods are used in labeling various groups. One way is to number the groups from one to 18 all the way across the periodic table, from the left hand side to the right hand side. Group one elements are known as alkali metals while group two elements are called alkaline earths. Group 17 are referred to as the halogens while group 18 are designated as noble gases, otherwise known as inert gases.
Noble gases are characterized by their nonreactivity with other chemical elements. These gases include helium, argon, radon, krypton, neon and xenon. The reason why noble gases are chemically inert is because of a filled octet that contain eight valence electrons. A full octet signifies that an element is less likely to lose, gain or share electrons, hence, noble gases remain inert and do not readily form chemical bonds with other elements.Learn more about Atoms & Molecules
A molecule is made up of two or more atoms of the same element or compound, or different elements or compounds, that are chemically bound together. A molecule is a quantity of a substance that can be measured by a chosen unit. Molecules are extremely small particles.Full Answer >
Gases are classified as oxidizers, inert or flammable. A gas that is an oxidizer is not flammable but does contribute to a combustion reaction. Inert gases do not partake in combustion reactions and do not react with other materials. Flammable gases react with air or oxygen and burn or explode.Full Answer >
The most characteristic property of the noble gases is their extremely low chemical reactivity as compared to other elements. The noble gases all have a full set of electrons in their outer shells, so they have little tendency to trade electrons with other elements to form compounds.Full Answer >
Arsenic is typically classified as a metalloid element and may be found in several mineral forms in nature. It is commonly dispersed in small amounts in soil, as well as in larger amounts in gold, copper, lead and zinc ores.Full Answer >
