NITROGEN- BACKGROUND INFO
My element is nitrogen. Discovered by Daniel Rutherford in 1772, he found that after he removed all the oxygen and carbon dioxide, the residual gas could not support combustion or life. However, Rutherford was not the only one to work with nitrogen. These researchers included Carl Wilhelm Scheele, Henry Cavendish, Joseph Priestley, and others. Originally, French chemist Antoine Laurent Lavoisier named nitrogen azote, or "without life", but it eventually was given its current name, nitrogen, from the Latin word nitrum (Greek nitron), meaning "native soda" and the Greek word genēs, or "forming." It is in the second period, meaning it has two electron shells, and the 15th group, meaning that it has 5 valence electrons and a oxidation number of -3. Its chemical symbol is N.
