Lead

Lead (/lɛd/) is a chemical element in the carbon group with symbol Pb (from Latin: plumbum) and atomic number 82. It is a soft, malleable and heavy post-transition metal. Freshly cut, solid lead has a bluish-white color that soon tarnishes to a dull grayish color when exposed to air; the liquid metal has shiny chrome-silver luster. Lead is the heaviest (has the highest atomic number) non-radioactive element (two radioactive elements, namely technetium and promethium, are lighter), although the next higher element, bismuth, has one isotope with a half-life that is so long (over one billion times the estimated age of the universe) that it can be considered stable. Lead's four stable isotopes each have 82 protons, a magic number in the nuclear shell model of atomic nuclei. The isotope lead-208 also has 126 neutrons, another magic number, and is hence double magic, a property that grants it enhanced stability: lead-208 is the heaviest known stable nuclide.

Lead is used in building construction, lead-acid batteries, bullets and shot, weights, as part of solders, pewters, fusible alloys, and as a radiation shield.

Last Week Tonight with John Oliver

Last Week Tonight with John Oliver, often abridged as Last Week Tonight, is an American late-night talk and news satire television program airing on Sundays on HBO in the United States and HBO Canada, and on Mondays (originally Tuesdays) on Sky Atlantic in the United Kingdom. The half-hour long show premiered on Sunday, April 27, 2014, and is hosted by comedian John Oliver. Last Week Tonight shares some similarities with Comedy Central's The Daily Show with Jon Stewart, where Oliver was previously featured as a correspondent and fill-in host, as it takes a satirical look at news, politics and current events on a weekly basis.

Oliver has said that he has full creative freedom, including free rein to criticize corporations. His initial contract with HBO was for two years with an option for extension. In February 2015, it was announced that the show has been renewed for two additional seasons of 35 episodes each. Oliver and HBO programming president Michael Lombardo have discussed extending the show from half an hour to a full hour and airing more than once a week after Oliver "gets his feet under him".
