# Explain why the metallic bonds in some metals are stronger than bonds in other metals?

Nov 8, 2015

The $d$-block metals have more valence electrons to contribute, and thus the positive ions in a sea of electrons, become more positive (because they have lost more electrons), and there is a greater density of electron "sea". This is an area where simple chemical considerations lead on to band structure, which I am reluctant (and incompetent!) to discuss.
