2.3.3 (HL)—Transition elements question 1
[Maximum number: 1]
Titanium and vanadium are consecutive elements in the first transition metal series.
Suggest why the melting point of vanadium is higher than that of titanium.
vanadium has smaller ionic radius «leading to stronger metallic bonding»
Marking guidance:
Accept vanadium has "one" more valence electron«s» «leading to stronger metallic bonding". Accept "atomic" for "ionic".
