Bond length effect on bond strength

Postby Austin Clack » Wed Nov 07, 2018 3:59 pm

So I know Professor Lavelle discussed the relationship between bond length and the corresponding strength of this bond. Shorter bonds = stronger bonds, but can someone explain why this is the case? is it because a shorter distance means the atoms' electrons are closer to the protons?

You got it! The larger an atom's radius, the longer its bond will be with another atom and the weaker the pull is between its protons and electrons.

Adding on, when you have two atoms bonded together, a larger radius means that the center of each atom is further apart. When the bond is shorter, the atoms are closer together and the attractive force between the protons of one and electrons of the other are stronger.
