Polar Covalent Bonds

If covalently bonded atoms have different electronegativities the distribution of electron density will be more towards the more electronegative atom which will acquire a slight negative charge.There is a continuum of bonding type from pure ionic to pure covalent.A polar covalent bond is a covalent bond that has some degree of ionic character.
