Covalent Bond Strength

Postby Danielle_Gallandt3I » Fri Nov 16, 2018 2:38 pm

Why is it that as atomic radii increases the strength of the covalent bond also increases? Wouldn't you want the atomic radii to be smaller to decrease bond length and strengthen the bond?

I'm pretty sure it does decrease with increased length. Refer to Coulomb's law: as radius increases force of attraction decreases

I believe you are right that as a bond get's longer, it's of weaker strength. Do you have an example which said otherwise? Also note that a double bond would be stronger than a single bond.

That is what I thought but in discussion my T.A. said that covalent bond strength increases with atomic radii
