Nitrogen is a gas without odor and color, which is very important for chemical industry and agriculture since it is essential for plant growth and often added to soils with fertilizers. Nitrogen gas is composed of the molecules which have two atoms of this chemical element, and the bond between the two is very strong. Nitrogen exists in abundance in the air, and that’s where it is consumed from by plants, for further use in DNA or RNA formation, and other formation processes. This chemical element is used in various industries like electronics for producing transistors, diodes, etc., in chemical industry to produce ammonia, in food industry for producing refrigerants, as explosives. Nitrogen is used to fill up tires, and the compounds of nitrogen are used as cleaners, anesthetic agents, as well as fuel for planes.

In the modern periodic table, the elements are listed in order of increasing atomic number. The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present). The number of protons determines how many electrons surround the nucleus, and it is the arrangement of these electrons that determines most of the chemical behavior of an element.
In a periodic table arranged in order of increasing atomic number, elements having similar chemical properties naturally line up in the same column (group). For instance, all of the elements in Group 1A are relatively soft metals, react violently with water, and form 1+ charges; all of the elements in Group 8A are unreactive, monatomic gases at room temperature, etc. In other words, there is a periodic repetition of the properties of the chemical elements with increasing mass.
The Atomic Number For Nitrogen-15
In the original periodic table published by Dimitri Mendeleev in 1869, the elements were arranged according to increasing atomic mass— at that time, the nucleus had not yet been discovered, and there was no understanding at all of the interior structure of the atom, so atomic mass was the only guide to use. Once the structure of the nucleus was understood, it became clear that it was the atomic number that governed the properties of the elements.
