This number is the atomic number. Melting point of Nitrogen is -209,9 °C and its the boiling point is -195,8 °C.
Subtracting the number of protons (7) from the element's mass number (14) makes it possible to determine the number of neutrons in the atom. It makes up about 78.1% of our atmosphere. 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. And its use as ammonium chdirde has been known … If there is a second letter, it is lowercase. Compounds of nitrogen were known in the middle ages.
It's the most common uncombined (pure) element on Earth. The chemical symbol for Nitrogen is N. Nitrogen is a colourless, odourless unreactive gas that forms about 78% of the earth’s atmosphere. Many nitrogen atoms have seven neutrons (14-7 = 7). The atomic number of nitrogen is 7. Atomic weight of Nitrogen is 14.007 u or g/mol. Its atomic weight is 14.0067. Atomic Number of Nitrogen Nitrogen is a chemical element with atomic number 7 which means there are 7 protons and 7 electrons in the atomic structure. Its element symbol is N. Nitrogen is odorless, tasteless, and colorless gas at room temperature and pressure. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images.
