The melting and boiling points of transition elements are generally high. Across the period, it first increases , reaches a maximum and then decreases. Due to formation of very strong metallic bonds which in turn depend on no. of unpaired electrons; transition metals have high melting and boiling points.
Zinc (Zn) has lowest melting point in 3d series because of absence of d-electrons.
