Negative reduction potential
Alkali metal ions -- on the very left edge of the periodic table, such as potassium or cesium -- have very negative reduction potentials. These ions are very difficult to reduce. These trends are not surprising, because alkali metals are generally at the lower end of the electronegativity scale (Table A2) and are typically found as cations, not ...
Transport corridors—large highways, railways, and waterways connecting countries and continents—offer enormous potential to boost Asia's economic growth, spur job creation, and reduce poverty, if the new trade routes spread their benefits widely and limit negative environmental impacts. But countries need to change the mindset that transport corridors are mere engineering feats designed ...
