Why is the boiling point of iron higher than magnesium? 




There are two main reasons:


1. Metallic bonding is more prevalent for transition metal elements because there are more electrons available for delocalization (from s and d orbitals), while Magnesium has only s electrons
2. Fe has a higher atomic mass than Mg --> van der Waals forces are stronger.
