Chemistry . * Examples include noble gases ie helium, neon, krypton, argon, etc * They don't react basically because they have already attained a stable electronic configuration and octet or duplet valence shell structure hence need not involve themselves in chemical reactio. A compound is classed as air-sensitive if it reacts with O 2, water, N 2, or CO 2. inert material containing certain chemical substances which serve as food constituents. Inert electrode is an electrode that does not participate in the chemical reaction. Mesoporous thin films are widely used for applications in need of high surface area and good mass and charge transport properties. The noble gases were described as being inert because they did not react with the other elements or themselves. All of this is divided into the production of advanced inert compounds that are dependent on a particular fusion process. Inert gases are present on the extreme right of the periodic table i.e., in group 18. They are generally colourless, odourless and tasteless and non-inflammable gas. Also, inert gases have stable electronic configurations i.e., complete octet or duplet. 1. Inert Anodes Inert anodes have been considered for years to be the future of aluminum production. In metallurgical processes, argon is widely used in order to provide the necessary inert atmosphere. At constant pressure, the addition of inert gas increases the volume, so increase the product formation. Inert material means a substance that will not decompose, dissolve, or in any other way form a contaminated leachate upon contact with water, or other liquids determined by the department as likely to be found at the disposal area, percolating through the substance."
