Question: Nitrogen is a chemical element with symbol N and atomic number 7. It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772. Although Carl Wilhelm Scheele and Henry Cavendish had independently done so at about the same time, Rutherford is generally accorded the credit because his work was published first. The name "nitrogen" was suggested by Jean-Antoine-Claude Chaptal in 1790, when it was found that nitrogen was present in nitric acid and nitrates; this name derives from the Greek roots νἰτρον "nitre" and -γεννᾶν "to form". Antoine Lavoisier suggested instead the name azote, from the Greek άζωτικός "no life", as it is an asphyxiant gas; his name is instead used in many languages, such as French, Russian, and Turkish, and appears in the English names of some nitrogen compounds such as hydrazine, azides and azo compounds. 

Nitrogen is the lightest member of group 15 of the periodic table, often called the pnictogens. The name comes from the Greek πνίγειν "to choke", directly referencing nitrogen's asphyxiating properties. It is a common element in the universe, estimated at about seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element bind to form dinitrogen, a colourless and odorless diatomic gas with the formula N. Dinitrogen forms about 78% of Earth's atmosphere, making it the most abundant uncombined element. Nitrogen occurs in all organisms, primarily in amino acids (and thus proteins), in the nucleic acids (DNA and RNA) and in the energy transfer molecule adenosine triphosphate. The human body contains about 3% nitrogen by mass, the fourth most abundant element in the body after oxygen, carbon, and hydrogen. The nitrogen cycle describes movement of the element from the air, into the biosphere and organic compounds, then back into the atmosphere. 1. What is the lightest member of group 15?

Question: Jamie Oliver has been invited by Gordon Brown to prepare a banquet at No.10 for President Barack Obama and other leaders of the G20, offering a cut-price menu to reflect times when trade and industry are far from prosperous and the rate of employment is decreasing. 

Downing Street sources say Oliver, the well-known chef, will cook using "honest high-street products" and avoid expensive or "fancy" ingredients. 

The prime minister is trying to avoid a repeat of the embarrassment last year when he sat down to an 18-course banquet at a Japanese summit to discuss world food shortages. 

Obama, President Nicolas Sarkozy of France, Chancellor Angela Merkel of Germany and other leaders will be served by apprentices from Fifteen, the London restaurant Oliver founded to help train young people in poverty in order to make a living by mastering a skill. 

Brown wants the dinner to reflect the emphasis of the London summit, which he hopes will lead to an agreement to lift the world out of recession."To be invited to cook for such an important group of people, who are trying to solve some of the world's major problems, is really a privilege," said Oliver. 

"I'm hoping the menu I'm working on will show British food and produce is some of the best in the world, but also show we have pioneered a high-quality apprentice scheme at Fifteen London that is giving young people a skill to be proud of." 

The chef has not yet finalized me menu, but is expected to draw inspiration from his latest book, Jamie's Ministry of Food, which has budget recipes for beef and ale stew and "impressive" chocolate fudge cake. (
