What happens when francium and nitrogen are mixed

At much higher temperatures, nitrogen reacts with oxygen to form nitric oxide, but this takes a considerable spark of energy. In the upper atmosphere during a lightning storm, nitrogen and oxygen react and the resulting nitric oxide further reacts with water to form nitric acid. When it rains, this nitric acid is carried down to Earth and forms compounds with other elements. Nitrates and nitrites are a few of the results.
