Hybridization can be defined as combining orbitals to form a new element. that that covalent bond consists of two electrons. Bromine trifluoride and bromine are formed as a result of this reaction. Dipole moments are caused by changes in electro negativity, which can occur between two ions in an ionic bond or between atoms in a covalent link. exact same situation. The overall formal charge in BrO3- is -1. Another example of a temporary dipole moment is when a molecules which are apparently non-polar (but even polar ones) are affected by electric fields so that they can become slightly polar.there are other examples of temporary dipole moments but they are quite complex..
