The difference is the degree to which the atoms forming the bond share their electrons.
In an ionic bond - say, between the sodium and chlorine atoms in table salt - the chlorine atom completely dominates the interaction, taking one electron from the sodium atom. This makes the chlorine atom a negatively charged ion and the sodium atom a positively charged ion. The bond between them is primarily due to the electromagnetic attraction between these positively and negatively charged ions - hence the name "ionic bond".
In a covalent bond - say, between the carbon and oxygen atoms in carbon monoxide - the electrons are shared much more evenly between the two atoms. True, the bonding electrons are more attracted to the oxygen atom because it has more protons in its nucleus than the carbon atom, but not to the same degree as in an ionic bond. The covalent bond between the atoms is primarily due to the stabilization that both atoms experience from this more or less even sharing of electrons.

What large differences in electronegativity result in bonding between atoms?
If this difference is under 2 the bond is covalent; if the difference is over 2 the bond is ionic.
What is the difference between ionic bond and covalent bond?
Ionic bond: involve an electrostatic attraction between atoms.Covalent bond: electrons are shared between atoms.
What type of bond is between Metals with nonmetals of differing electronegativities?
If the difference in electronegativity between the metal and the non metal is above 1.7, then ionic bond is formed. If the difference in electronegativity between the metal and the non metal is below 1.7, then polar covalent bond is formed.
Is MgCl2 a polar covalent bond a covalent bond or an ionic bond?
MgCl2 is an ionic compound. there is a large difference in electronegativity between Mg and Cl.
When does and ionic bond form between a metal and a nonmetal?
If the difference in the electronegativity between the two atoms is above 1.7, then an ionic bond is formed.
What is the difference between an ionic bond covalent bond and hydrogen bond?
ionic bond: between a metal and a nonmetal Covalent bond: between 2 non metals USUALLY and i don't know about hydrogen bonds...
What is the difference between and ionic bond and a convalent bond?
A covalent bond occurs when two Klingons get it on. An ionic bond occurs when a Cardassian and a Floopite hit the hay.
What is the difference between metals and ionic bonds?
Ionic bond is the bond between anion and cation whereas metallic bond is the come between the molecules of the metal atom
What is the primary difference between a ionic and covalent bond?
In an ionic bond electrons are transferred and the bond is due to electrostatic attrcation between oppositely charged ions. in a covalent bond the electrons are shared .
What type of bond will form between atoms of calcium (Ca) and fluorine (F)?
Ionic bond, as the difference in electronegativity between calcium and fluorine is over 1.7
What is a rule for predicting whether or not a bond will be ionic?
If the difference in electronegativity between the elements is greater than 2 then the bond will be ionic, if its between 1.6 and 2 then it will be ionic if one of the elements is a metal.
Why doesn't silicon form an ionic bond with boron?
Because the difference in their electronegativity is not sufficiently large.See the Related Questions to the left for the difference between a covalent and an ionic bond.
