Which bond is stronger? Ionic or covalent? I've gotten conflicted answers when I googled this question online.

Generally speaking, ionic bonds are stronger than covalent bonds.

I also agree that ionic bonds are stronger than covalent bonds.

Ionic bond is generally stronger because the ion-ion force that exists in ionic bonding is the strongest. In covalent bonds, electrons are shared, which doesn't generate a force as strong as that in ionic bonding. This can also be explained when we compare the boiling points of ionic compounds and covalent compounds. Ionic compounds' boiling points are generally higher than covalent compounds' because it takes more energy to break the bonds in between ionic compounds.

Ionic bonds are usually stronger than covalent bonds. A defining characteristic of ionic bonds is that an electron from one atom is "taken" by another atom, whereas in covalent bonds, the electron is shared between the two atoms.

Ionic Bonds are stronger than covalent bonds because the electronegativity difference between the two elements is much greater than that of two elements in a covalent bond. Covalent bonds allow the electrons to be shared between the two elements and will often favor one element over the other depending on polarity.

Ionic bonds are usually stronger than covalent bonds because there is an attraction between oppositely charged ions. But, when molecules with ionic bonds are dissolved in water the ionic bonds become much weaker in comparison to covalent bonds after molecules with covalent bonds have been dissolved in water. This could possibly be the reason you are finding different answers.

Ionic bonds are stronger than covalent bonds due to the fact that they involve the transfer of electrons rather than an equal sharing of electrons, which occurs within covalent bonds, and usually, more energy is required to dissociate ionic bonds.

covalent network are the strongest (ex. diamond and graphite) are stronger than ionic however covalent bonds themselves are usually weaker than ionic bonds.

Most often Ionic bonds are stronger than covalent bonds; however, there are some covalent bonds stronger than ionic.
Ionic bonds are formed as a result of a mutual attraction between ions that have opposite charges. Covalent bonds are formed as a result of the sharing of electrons. Ionic bonds are stronger because of coulombic attraction

Ionic bonds are stronger than covalent bonds, because there is a stronger attraction between ions that have opposite charges, which is why it takes a lot of energy to separate them. Covalent bonds are bonds that involve the sharing of electron pairs between atoms.

When compared to ionic bonds IN water, covalent bonds are stronger.

Ionic bonds are way stronger than covalent unless you look for the hydrogen bonding with fluorine, nitrogen, and oxygen. It depends on the interactions between the atoms that causes the differences.

Ionic bonds are stronger than covalent bonds, but when dissolved in water, they become much weaker because ions separate and are surrounded by water molecules.

Just curious. Does anyone know if polarity affects bond strength? If so, how?

How much of knowledge like this will be required for the final in this class?

In space or air, ionic bonds are much stronger than covalent bonds. However, since molecules with ionic bonds can be dissolved in water, covalent bonds are stronger in water than ionic bonds.

I think in general, ionic bonds are stronger than covalent bonds. But covalent bonds are stronger than ionic bonds in water.

Right now, we haven't gotten to covalent networks, but in general, covalent bonds that are not arranged in special formations are generally weaker than ionic bonds.

Ionic bonds are stronger than covalent bonds because covalent bonds share an electron.

It should be noted that water can weaken an ionic bond so in that case a covalent bond may be stronger.

Ionic bonds are much stronger since electrons from one atom is given to another and the two atoms basically are glued together through the bond. On the other hand, in covalent bonds the atoms are merely 50/50 sharing the electrons, therefore not as strong as an ionic bond.

Ionic bonds are stronger than covalent bonds because elements give/take electrons, whereas elements with covalent bonds share electrons.

Ionic bonds are stronger than covalent bonds. However, in water, ionic bonds are weaker. This is why you might hear that covalent bonds are stronger in your biology classes.

Typically, ionic bonds are stronger but there are exceptions such as weakened ionic bonds as water as well as special strengthened covalent bonds known as covalent network bonding.

In natural life, covalent bonds are stronger than ionic bonds due to the natural aqueous state that surrounds us. Because ionic bonds become weak when placed in water/polar-aqueous solution. In a theoretical "dry/non-aqueous" world, ionic bonds are stronger than covalent bonds.
In other words, in biology, covalent bonds > ionic bonds.
In chemistry, ionic bonds > covalent bonds.
