The Lewis Structure or the Lewis Dot Structure or the Lewis Dot Diagram, named after Gilbert N. Lewis, shows the diagram of the atomic bonding of the molecules or an element. It shows the lone pairs of molecules existing in a molecule. A Lewis Structure can be drawn or presented both in case of the covalently bonded molecule and for the coordination compounds.

The Lewis Structure shows the positions of each of the atoms and also shows the molecular bonding of the element or the molecule, using its chemical symbols. The electrons which are bonded with one another are showed by drawing lines, and the excess electrons, which forms the lone pairs are shown with dots.

The following is the Lewis Dot Structure for N2,

2N and N2, are basically two forms of the same element. There is a little difference between the two. 2N refers to two molecules of Nitrogen atom, and N2 states that two atoms of Nitrogen are present in a single molecule. The number written at the start, refers to the number of molecules and the number written in the subscript refers to the numbers of Atom presented.

Nitrogen is a triple bonded molecule. Since Nitrogen belongs to the diatomic molecule in the VA family, on the periodic tables, which means that the valency of the molecule is five, therefore, it needs three more valences of electrons in order to complete its octet, and therefore, it is a triple bonded molecule. The Nitrogen atom, therefore, fills its octet by sharing three electrons of another nitrogen atom, with the triple bonds or the covalent bonds and thus creates, N2, that is two atoms in a single Nitrogen molecule. The formation is,

The formula of Nitrogen Gas is,

Nitrogen gas is a diatomic element, which refers, one molecule Nitrogen is consisted of two atoms of same element with three covalent bonds.

The formation of Nitrogen is done by the covalent bonding. Each of the Nitrogen has 5 electrons. The first sell is 1s, which is consisted of 1electron, and takes two electrons, and thus, is filled. The next sell has two sub sells, 2s and 2p. 2s is filled, but 2p is not, and is consisted of only 3 electrons, and therefore, to get the stability, and to have an equivalent number of 8 electrons, 2p accepts another electron, and thus, the two atoms of Nitrogen come together, sharing three electrons, to get stability, and thus, the nitrogen gas is formed.
