Iodine is an element that exhibits non-polar, covalent bonding, notes Elmhurst College. It has seven electrons in its outer shell. When bonded to another iodine atom, the two equally share two electrons to complete the eight needed to form an octet.Continue Reading
There are non-polar and polar covalent bonds. Non-polar covalent bonding is the equal sharing of electrons between two identical non-metals. Polar covalent bonding occurs when two different non-metals unequally share electrons.
Water, with the formula H20, is an example of polar bonding. Oxygen is bonded to two hydrogen atoms. Oxygen has six electrons in its outer-shell, while hydrogen contains one. Collectively, they have eight electrons to form an octet, but the electrons spend more time near the oxygen atom.Learn more about Chemistry
