It is a metal sulfide that, like other sulfides in its neighboring spots in the periodic table, is also only sparingly soluble in water. At room temperature, only a small amount of PbS will dissolve in water, resulting in a very low concentration of dissolved Pb2+ and S2- ions. This so...

Cd-preferred or non-preferential PSLs (Pb/Cd-preferred means that the Pb/Cd–PSL interactions are stronger than the Cd/Pb–PSL interactions; non-preferential means that the Cd–PSL and Pb–PSL interactions are equivalent, see Supplementary Discussion, Supplementary Table 1 and Supplementary Fig. ...
Caught up in the race to discover the atom’s internal parts — and learn how they fit together — a young British physicist named Harry Moseley uses newly discovered X-rays to put the Periodic Table in a whole new light. And a young American chemist named Glenn Seaborg creates a new ele...
