It is defined as the equilibrium pressure exerted by the gas produced above a substance in a closed system. Please enable JavaScript to access the full features of the site. Two of the electrons are in the. While other scientists had tried to create ways of ordering the known elements, Mendeleev created the system that could predict the existence of elements, not yet discovered. Element Nitrogen (N), Group 15, Atomic Number 7, p-block, Mass 14.007. See you next time. 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. Click here to view videos about  Nitrogen, It’s Elemental - The Periodic Table of Elements. This refers to the choking property of nitrogen gas (as opposed to air, which contains oxygen as well as nitrogen). Thus, the number of valence electrons of nitrogen is 5. Atomic Number – Protons, Electrons and Neutrons in Nitrogen Nitrogen is a chemical element with atomic number 7 which means there are 7 protons in its nucleus. It has been used as a poison and as a rodenticide. It is estimated to be the 7th most abundant chemical element in our universe. We welcome your feedback. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). Element density increases moving down the family.
