Increase in the difference in electronegativity along a bond increases the percent ionic character of the bond (how similar it is to an ionic bond). Small to intermediate differences would result in polar covalent bonds and large differences leads to the formation of an ionic bond rather than a covalent bond.

The more electronegative atom will make its end of the bond more negative.

Can you predict boiling point of a compound with the help of boiling points of elements in it?
The intra and inter molecular forces will help to determine the higher boiling.Intra molecular forces are Polar/Non-polar covalent bonds and ionic bonds. Covalent bonds are stronger than ionic bonds.Polar covalent bonds will have a higher boiling point because non-polar covalent bonds are only affected by London forces.Intermolecular forces are hydrogen bonding, diapole-diapole and London. All molecules have London forces.Also the higher the electro-negativity the higher the boiling point.If all of the intra and inter molecular forces are the same, refer to the electro-negativity and size. The greater the electro-negativity and size, the higher the boiling point.
Does the NH3 molecule contain polar bonds?
Yes Because the electro-negativity number of N is 3.0 - the electro-negativity number of H is 2.1 =.09 If two elements have an electro-negativity number between 0.5 and 2.1, it has a polar bond. Another way is that N and H are both non-metal and they have an unequal share of electron so it is a polar covalent bond.
Ionic bonds are between?
They are between two atoms.These atoms have high electro negativity difference
What is the attraction between molecules of ammonia?
Nitrogen and Hydrogen have high electro negativity difference.So they can form hydrogen bonds.
What type of bond will NH3 have?
N and H have a high electro negativity difference.And also have a lone pair.So hydrogen bonds are formed
Is bromine and ionic or covalent bond?
There is no electro negativity difference.The bond is covalent.

Is barium chloride ionic or covalent?
"It is ionic" but with covalent properties, due to the electro negativities of the two ions.
What property of metallic bonds affect the thermal and electrical conductivity of metals?
electron negativity
What percent of sharing of electrons in covalent bonds results in polar molecules?
In a polar covalent bond, the electrons shared by the atoms spend a greater amount of time, on average, closer to the oxygen nucleus than the hydrogen nucleus. This is because of the geometry of the molecule and the great electro-negativity difference between the hydrogen atom and the oxygen atom.
Why h20 has high hydrogen bonding then h2s?
H and O have much electro negativity difference.H and S do not have much difference to make H bonds.
What kind of bond is NH3?
NH3 has triple bond
Covalent bonds form by atoms sharing electrons while ionic bonds?
Ionic bonds are formed by donating electrons from the electro positive atom to electro negative atom results in the formation of ions so that the opposite charged atoms combine to form a bond(ionic)with release of lattice energy.
