This element sits in period 2 and group 15 of the periodic table, and its electrons are arranged in shells of 2, 5. The short electron configuration of Nitrogen is [He] 2s² 2p³. Known uses of Nitrogen include Chemical fertilizers, Food storage and Electronics industry.
The electron configuration of Nitrogen (N), with 7 electrons, is shown below. The last shell (shell 2) is highlighted:
Distribution of 7 electrons of Nitrogen across shells K to L:
The nonmetals are usually poor conductors of heat and electricity and are brittle in solid form; they are the base elements of organic and biological chemistry.
The atomic number of Nitrogen (N) is 7; that is, every atom of it has 7 protons.
The electron configuration of Nitrogen (N) is 1s² 2s² 2p³; in short form it is [He] 2s² 2p³, and its last shell is 2s² 2p³.
