HalogenOxidantLatimer diagramEnthalpy of formationRedox potentialAlthough it is generally accepted that fluorine is the strongest oxidant among the halogens and so among all of the elements, it has not been explained in the literature why this is the case. In this paper, we ask whether this "...
Therefore group 1 metals will have very low electronegativity relative to group 7 elements (halogens). Combining two elements with strongly differing electronegativity values can result in an oxidation-reduction reaction and the formation of an ionic bond, which is considered to ...
When freshly cut, lead is silvery with a hint of blue; it tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is a relatively un...
