Because Nitrogen has 7 protons in its nucleus and 7 electrons around it. In this one s orbital and three p orbitals of Carbon atom hybridize and form a sp3 hybridization HCN Lewis Structure, Molecular Geometry, Shape, and Polarity. Then the remaining eight electrons will enter the 4f orbital. There are two obvious ways to build the Lewis structure there are two resulting molecules that exist, hydrogen cyanide (HCN) and hydrogen isocyanide (HNC). Calculate the number of valence electrons. Now, hybridize to explain the bonds. The remaining two valence electrons are "paired", and this notation implies that they therefore are not generally available for sharing in a covalent bond {H_2CO}\); and hydrogen cyanide, \(\ce{HCN}\). Include all lone pairs of electrons Count the total number of valence electrons by adding the valence electrons from Hydrogen (), Carbon (), and Nitrogen (), which are , , and respectively Lewis Symbols. Hydrogen can only hold 2 electrons in its outer shell, therefore it's completed by the single bond. Follow the 6 steps to find the center atom, complete the octet, and check the stability of the lewis structure.
