Two atoms of the same non-metal element, always.

In all other cases, there's at least a slight difference in electronegativity.

For example, two atoms of Cl form Cl-Cl (Cl2), which is a non-polar molecule.

A covalent bond formed between two elements that have an electronegativity difference of 1.6 would be?

a very polar bond.


What term describes a covalent bond in which electrons are not shared equally?

A polar covalent bond. In a polar covalent bond, one atom has a greater electronegativity than the other, causing the electrons to be pulled towards that atom, creating a partial positive and partial negative charge on the atoms.


What does a covalent bond mean?

It just means a non-polar bond. If the difference in electronegativity between the two elements is less than .5, then it is a pure (non-polar) covalent bond.


Why a covalent bond becomes polar?

When the difference of the electronegativities of the two elements is significant.


Would H and S perform a polar covalent bond?

Yes. Sulfur (S) and hydrogen (H) will form a polar covalent bond.


What element is a polar covalent bond?

No single element can form a bond. Only 2 or more elements can form bonds. Polar bonds occur when there is a dipole moment, or there is asymmetry in the structure. For example, HF forms a polar covalent bond.


What is the difference in polar and non-polar covalent bonds?

In a polar covalent bond, the electrons are pulled more toward certain elements, giving them a partial charge. In a non polar bond, the electrons are evenly or close to evenly shared.


How does a polar covalent bond differ from a covalent bond?

Electrons are shared unequally in a polar bond.


Is sugar a polar covalent bond or nonpolar bond?

Sugar contains polar covalent bonds due to the electronegativity difference between the elements involved in the bond formation, like carbon, hydrogen, and oxygen. The presence of polar covalent bonds in sugar contributes to its overall polarity.


Does hydrochloric acid contain a non-polar covalent bond?

HCl (hydrogen chloride) has a covalent bond, polar.


Is SO2 non polar covalent polar covalent or ionic bond?

Polar covalent. The difference in electronegtivity is insufficient for an ionic bond


Does N2 contains a polar covalent bond?

No. It contains non-polar covalent bond.
