The Reactivity Series of Metals - Although most metals are usually electropositive in nature and lose electrons in a chemical reaction they do not react with the same vigour or speed. Metals display different reactions towards different substances. The greate..

Dihydrogen reacts with non-metals under specific conditions. Some of the reactions are: The reactivity of halogen towards dihydrogen decreases as: F 2 > Cl 2 > Br 2 > I 2 As a result, fluorine reacts in dark, chlorine in the presence of sunlight, bromine reacts only upon h..

As in the case of S, the important oxidation states observed for Se and Te are also 2, +2, +4 and +6. The chalcogenide dianions (E 2 - ) exist only in their compounds with the most electropositive elements. By and large, chalcogens with the exception of polonium, display non-metallic..

. They are generally brittle. Electronic configuration They usually have 1, 2 or 3 electrons in their valence shell. The greater the number of shells and lesser the number of valence electrons, the greater is the reactivity of the metal. They usually have 4, 5, 6 or 7 electrons ..

We are familiar with the fact that the atoms of all elements, except noble gases, have an incomplete outermost shell. Consequently, most elements are reactive and they try to achieve the stability of the noble or inert gases by electron transfer or by electron sharing. After this combina..

The reactivity of metals decreases from left to right in a period while the reactivity increases down the group. The reactivity of non-metals increases from left to right in a period while the reactivity decreases down the grou..
