Nonmetalsrepresent thetop rightof the periodic table. These elements are usually gases at room temperature and tend to form anions. Non-metals have the highest electronegativity of any of the elements, meaning they steal electrons. What are halogens? The halogen family is the maingroup sevenon ...
The seven elements—helium, neon, argon, krypton, xenon, radon, and oganesson—of Group 18 of the periodic table. All of the noble gases are present in Earth’s atmosphere and are colorless, odorless, tasteless, and nonflammable. Learn more about noble g
The results reveal that similar responses to those obtained with thermally activated sensors can be achieved by choosing the optimal illumination conditions. This finding paves the way to the development of conductometric gas sensors operated at room temperature. The power consumption in these devices ...
Uranium and Plutonium have ominous uses that speak for themselves. The Inert Gases are "Noble" for not forming compounds with other elements -- the electron shells have filled up and are stable. Purple is used here for its Imperial associations. The most reactive elements, are those an electro...
and, at constant pressure, increase its volume. This expansion of air results in work beingdone. In the cylinder of aninternal-combustion engine, for example, the combustion of gasoline results in hot gases that expand against a moving piston. The motion of the piston turns a crankshaft, ...

The periodicity of properties of the elements is caused by the periodicity inelectronic structure. The noble gases are chemically unreactive, or nearly so, because their electronic structures are stable—their atoms hold their quota of electrons strongly, have noaffinityfor more electrons, and have ...
Burning is a widespread practice for pruning remains management, which implies fire hazard [20], emission of greenhouse gases into the atmosphere, assuming a reduction in carbon sequestration, as well as loss of elements and nutrients that compose them [13,21]. Moreover, the Member States of ...
