Explanation An atom is neutral because the number of protons and the number electrons are equal to each other. The rearrangement/sharing of electrons between two atoms create a force between the two atoms. The atoms are held together as a molecule due to this force. This force is often referred to as chemical bond . The electrons shared between the atoms have to be symmetrically distributed between the atoms in equal magnitude. But there are certain factors that impact the symmetrical distribution of bonding electrons between atoms. When there is unsymmetrical distribution of electrons between two atoms the electron cloud becomes condensed particularly near to one of the atoms. Consequently, the atom in which electron cloud is near to it acquires partial negative charge and the other atom acquires partial positive charge. This phenomenon is termed as polarization. Such a chemical bond is called polar bond and the molecule is called polar molecule. dipole moment is measure of polarity in the chemical bond. In Boron trifluoride three F-atoms are bonded to Boron atom. The Boron atom occupies the center position and the three F-atoms occupy the corner positions of a trigonal plane as follows – Figure 1 The angle between the three F-atoms is 120 °
