∙ 11y agoThe bond becomes polar because the sharing of electrons are unequal on the poles (sides of the molecule). So the side with more electrons becomes more negatively charged, and the side with less electrons becomes more positively charged. For example, water is polar because the oxygen atom doesn't share the hydrogen atoms equally.

∙ 13y agoA covalent bond is a chemical bond between two or more non-metalic elements. Only bonds between the same elements are truly nonpolar. The higher the difference in electronegativity, the more polar the bond is.

∙ 13y agoAll elements have a property called "electronegativity". In any molecular bond, electrons are shared. A very electronegative element will keep the shared electrons closer to itself causing itself to have a slightly negative charge. This is a polar bond. Put simply: polar bonds occur between atoms of differing electronegativities.

∙ 15y agoIf the bond is between two atoms with different electronegativity then the atom with the higher electronegativity will attract the electrons in the bond more and will result in a higher electron density on one side of the bond. This is what we call polar.
Imagine taking two equal magnets and putting them on a desk with metal filings. The filings will be equally attracted to both magnets. Now image replacing one magnet with an ultra strong magnet. The filings will mostly gather around this stronger magnet.

∙ 13y agoOne must be higher than the other to form a polar molecule. This is because one side will be more negative than the other.

What do electrons do for polar covalent?
When the difference of the electronegativities of the atoms is significanct the bond is covalent polar. The electrons are of course shared.
How can the type of bond be predicted?
Ionic bond: the difference between electronegativities of the atoms is over 2.Covalent polar bond: the difference between electronegativities of the atoms is under 2.Covalent non-polar bond: the difference between electronegativities of the atoms is cca. zero
What is a polar covalent bond forms when two atoms?
A polar covalent bond is formed when the difference between electronegativities of two atoms is 0,4 to 1,7.
When atoms in a covalent bond have a rather high difference in the electronegativities the bond is set to be?
A polar covalent bond.
What does the presence of a polar covalent bond show about the electronegativites of its two atoms?
That the electronegativities of the two atoms are substantially different - enough so to cause polarity in the bond. However, the difference in electronegativities is not great enough to cause an ionic bond to be formed.
When atoms in a covalent bonds have a rather high difference in their electronegativities the bonds is said to be?
polar
When is a polar covalent bond is formed between two atoms?
if two combining atoms have a difference of electronegativities between 0.5 and 1.7 then bond formed is a polar covalent bond.
