Explain why the highest oxidation state for group 14 (IVA), +4, is exclusively observed for carbon but hard to stabilize for lead, which has +2 as its most stable oxidation state. When formulating your answer, also consider what oxidation states are typically exhibited by silicon, germanium and tin.
Lead which is 6th period element with outer shell configuration of 6s2 6p2. Here removing two electrons from p shell results in Pb2+ and its more stable than Pb4+ (which we get by removing 4 valence electrons). This is because of inert pair effect. The d shells in Lead are weak in shielding the nuclear charge and thus nucleus has hold the 6s electrons tighter and thus removing s electron requires more energy. Hence lead exist mostly as Pb2+ which is more stable than Pb4+. For lower period elements like Carbon there are no "d" shell electrons which have weak shielding affect. Hence +4 is easily observed in carbon.
Then tendancy for +2 state increases as atom size increases i.e its order of C2+ < Si2+ < Ge2+ < Pb2+

1. Introduction In recent years, nanoclays have been the object of particular interest for many scientists and researchers in chemistry, physics, engineering and biology due to their excellent properties as well as their sustain- ability [1-3]. For instance, they represent the starting point to the de velopment of smart materials for drug delivery (4-9), food packaging [10-12), environmental remediation and wastewater treatment [13], cultural heritage [14–17and...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
