Question

Why are covalent bonds stronger than ionic bonds?? i recently read up that covalent bonds are generally stronger as using Coulomb's Law aid in the justification. But could someone care to explain further i'm kinda having a hard time understanding the theory. thx

Answer 1

In ionic bonds, both atoms are treated like point charges, hence the compound is polarized. Hence there is a higher tendency to break.

Answer 2

thanks but i want to ask a lil chem now about the question. The strength of the covalent bond increases down a group?? hmmm....u see i know as you go down the atom would gain a extra valent shell but aren't the energy lvl on the outer shell greater than the inner so it means that the bond strength would increase downwards right?? U see i'm not sure because i know electron shielding by the orbitals are usually taken into consideration when talking about bond between atoms and so on..

Answer 3

the valence electrons are more towards the centre of the bond as you move down the group
