Nitrogen

Sky blue ball=Nitrogen atom
Spring=covalent bond
Nitrogen molecule has a formula of N2 where 2 nitrogen atoms are connected in triple bond which are covalent bond in which three pairs of electrons are shared by two atoms. Also, there is one lone pair in each atom to satisfy octet rule. The nitrogen molecule is in a linear structure where two atoms in a line which mean there is a 180 degree bond angle in nitrogen molecule. In addition, the structure of nitrogen molecule in Lewis structure can be written as :N Ξ N:
