Pb, a chemical element in group IV of Mendeleev’s periodic system. Atomic number, 82; atomic mass, 207.2. A heavy, bluish gray metal, lead is very ductile and soft; it can be cut with a knife and scratched with a fingernail. Natural lead is composed of five stable isotopes, with mas...
Pb(IV) salts may be obtained by the electrolysis of solutions of Pb(II) salts strongly acidified with H2SO4. The most important Pb(IV) salts are the sulfate Pb(SO4)2 and the acetate Pb(C2H3O2)4. Pb(IV) salts tend to combine with excess negative ions to form complex anions, for ...
Lead monoxide, with the chemical formula PbO and CAS registry number 1317-36-8, is a compound known for its various applications. This inorganic compound is a yellowish or reddish-brown solid that is insoluble in water. Lead monoxide is commonly used as a pigment in paints, ceramics, and gl...
double perovskite materials with formula of A_2M(I)M(III)X_6 or A_2M(IV)X_6 could be potentially regarded as stable and green alternatives for optoelectronic applications, where two divalent lead ions are substituted by combining one monovalent and one trivalent ions, or one tetravalent ion....

Their mantle source was significantly influ- enced by interaction with asthenospheric (convective) mantle depleted in large-ion lithophile elements (Rock, 1991). This is in line with rift-related passive asthenospheric upwelling that resulted in the gener- ation of large volumes of Tertiary ...
Write a balanced equation to represent the oxidation of tin by nitrate ion in basic solution to yield tin(IV) oxide and nitrogen dioxide. Write a net ionic equation for the reaction that occurs, when aqueous solutions of sodium hydroxide and hydro...
