covalant bonds are stronger than ionic bonds?

Answer 1

Covalent bonds are stronger than ionic bonds, but ONLY on the AP Bio exam.

In reality, the bond strengths of covalent and ionic bonds (as determined by measurements of atom dissociation) tend to be very close to each other and even overlap.

For example, the Hydrogen-Hydrogen covalent bond is calculated at 4.52 eV. In comparison, the Sodium-Chloride ionic bond is usually calculated at 4.26 eV. However, the Sodium-Fluorine ionic bond is 4.99 eV and Lithium-Chloride is 4.86 eV.

The more data you look at the fuzzier this topic will become. Do not confuse the ease at which hundreds of water molecules (using Hydrogen bonding) can separate Sodium ions from Chloride ions in an aqueous solution but not separate the atoms of Ethanol as an example of "stronger bonds".

Answer 2

Yes, because the energy associated with shared pairs of electrons in covalent compounds carries a greater force of attraction than the electrostatic attraction found between positive and negative ions. This is because electron sharing involves actually merging the valence electron shells of two atoms into one, as opposed to ionic bonds, where the bond is simply caused by an electrostatic attraction between a positive ion and a negative one, sort of like static cling or magnets. The ions are still separate entities, just sort of "stuck" together.Thus it would take much less energy to break up this bond than it would to separate two atoms that are actually using the same valence shell and therefore functioning as a single particle.

Answer 3

Covalent Bonds-Covalent bonding is one in each and every of those chemical bonding between 2 non metallic atoms it quite is characterised via the sharing of pairs of electrons between atoms and different covalent bonds. A covalent bond is formed between 2 non-metals that have comparable electronegativities. Neither atom is "solid" adequate to entice electrons from the different. For stabilization, they share their electrons from outer molecular orbit with others Ionic Bonds-Ionic bond, additionally ordinary as electrovalent bond is one in each and every of those bond formed from the electrostatic attraction between oppositely charged ions in a chemical compound. a majority of those bonds ensue specifically between a metallic and a non metallic atom. An ionic bond is formed between a metallic and a non-metallic. Non-metals(-ve ion) are "better" than the metallic(+ve ion) and could get electrons very quite from the metallic. those 2 opposite ions entice one yet another and sort the ionic bond. EG: Covalent: Methane (CH4), Hydro Chloric acid (HCL), which factors are all nonmetals Ionic: Sodium chloride (NaCl), Sulphuric Acid (H2SO4 ) etc.

Answer 4

Yes.
