Polar Molecules In covalent bonds where electrons are shared between atoms, there is a partial transfer of electron density from one atom to the other. When two atoms have different electronegativities, partial ionic charges arise due to the unequal share of electrons. Becaus...
The contributing factors in determining polarity of molecules are the geometric shapes of the molecules and the type of bond between their atoms. When atoms chemically bond together, they either transfer or share electrons to bond and form a molecule. Whether atoms end up sharing or transferring ...
