Which is the strongest bond ionic covalent or metallic?

Answer 1

The relative strength of bonds is:

Covalent > Ionic > Metallic > Hydrogen Bonding > Van der Walls Dispersion Forces

This is only a general, as there are ionic substances that are quite strong, and relatively weak covalent substances. The strongest substances are network covalent, which includes diamond and, strangely enough, graphite.

lie in general the ionic bonds are stronger than covalent bonds

Answer 2

It depends on the atoms in the molecule. However, IN GENERAL:

Covalent > Ionic > Metallic > Hydrogen > Van der Waals forces

So yes covalent bonds are TYPICALLY stronger than metallic bonds. However, the energy of covalent bonds ranges from 150-1100 kJ/mol, ionic bonds range from 400-4000 kJ/mol, and metallic bonds range from 75-1000 kJ/mol. The strength of the bond just depends on what atoms are involved. For example, ionic H-F bonds are much stronger than covalent H-H bonds so there are certainly exceptions to this rule.

Answer 3

ionic bonds are stronger than the covalent.its because the covalent bonds are formed by sharing of electons and ionic bonds are formed by give and take of elecrons which complete the octates of atoms

Answer 4

Covalent and ionic bonds are bonds which can broken to release energy, they are formed when energy is transferred or a reaction takes place. This is in contrast to metallic bonds which freely share electrons and such bonds are specific to metals, giving the elements properties that are observed such as conductivity, maliability, ductility, etc..

In terms of energy store a covalent will hold more as when it breaks down it produces a +2 -2 charge(respective to the 2 elements).

Answer 5

Not a fair comparison. Some covalent bonds (like triple bonds) are very strong. Some ionic bonds (like Al2O3) are very strong. But if you were to ask on average, which is stronger I would have to say covalent. That being said, ionic compounds are much harder to break apart because you are usually not talking about a single ionic bond---ionic compounds form ionic lattices of many many ionic bonds. The only time that happens with covalent bonds is with network covalent compounds (like diamond) and those are notoriously hard to break up.

----------------------------------------------------------------------------- i agreed with what is said above but would like to add that another factor adding to strength to covalent bonds is the fact that they arise out of molecular orbitals and electrons actually interact with each other within these orbitals as wave functions, whereas ionic bonds are purely electrostatic attraction(colombic) and can be thought of as point charges with no electron interactions also keep in mind that there is no clear line between ionic and covalent in many compound but rather a gradient with some molecules that have partially characterisitics of both

Answer 6

The relative strength of bonds is:

Covalent > Ionic > Metallic > Hydrogen Bonding > Van der Walls Dispersion Forces
