Polarity is a theory in chemistry that tries to explain the unequal sharing or sharing of electrons. These types of sharing electrons define what type of bond a substance is. The bonds are either polar, meaning that the substance has an unequal sharing of electrons, like water, or if it is non-polar, meaning the substance has an almost uniform electric balance, like methane. Also, polarity can also affect the physical characteristics of a substance like melting point, boiling point, freezing point, etc.
The pull between the elements is considered electro negativity, and it is measured and justified by the formation of an electric dipole. What a dipole is is a separation of positive and negative charges into two poles. Furthermore, whichever element has more pull is deemed delta negative, represented by the greek symbol for delta, also with a negative sign. The one with the least pull is deemed delta positive.
