The D-And-f-Block Elements
Question
Why the melting points of transition elements are high?
Solution
The melting points of transition elements are high due to the presence of strong intermetallic bonds (formed by valence electrons) and covalent bonds (formed due to d-d overlapping of unpaired d-electrons).
