The purpose of a Review is to bring the reader up-to-date with research in a particular area. Periodic Trends in the Electronegativities of Elements. Plays-/5-RATE QUIZ. As we move across a period from left to right the nuclear charge increases and the atomic size decreases, therefore the value of electronegativity increases across a period in the modern periodic table. Teaching and learning methods. The Fenton reaction- based process, which is exothermic and generally carried out at a temperature higher than ambient temperature, is commonly applied as a pretreatment process for wastewater resistant to biological treatment and/or toxic to biomass.
