Write an electron configuration for N. Then write a Lewis symbol for N and show which electrons from the electron configuration are included in the Lewis symbol.
Solution:Step-1Bond Dipole:-The bond dipole moment uses the idea of electric dipole moment to measure the polarity of achemical bond within a molecule. It occurs whenever there is a separation of positive andnegative charges.The bond dipole is given by:= ×dThe bond dipole is modeled as + — - with a distance d between the partial charges + and -.It is a vector, parallel to the bond axis, pointing from minus to plus, as is conventional forelectric dipole moment vectors.For exampleA diagram showing the bond dipole moments of boron trifluoride. - shows an increase innegative charge and + shows an increase in positive charge. Note that the dipole momentsdrawn in this diagram should be from - to + as discussed in textStep-2Molecular Dipole:-Even though the total charge on a molecule is zero, the nature of chemical bonds is such that thepositive and negative charges do not completely overlap in most molecules. Such molecules aresaid to be polar because they possess a permanent dipole moment. A good example is the dipole moment of the water molecule.\n
