WebThere are four main areas we need to consider in answering this question. The first is Sodium, Magnesium and Aluminium. These are all metals and so have a metallic bonding structure. As you go across the period, the atomic radii decreases. This is due to an increased positive charge of the nucleus (increased electronegativity) pulling the outer ... WebIn general, the melting points of transition metals are much higher than those of main-group metals. The outermost as well as inner shell electrons contribute to the bonding in transition metals. Across Period 4 in the periodic table, the melting points of 3d transition metal elements show a maximal peak around vanadium and chromium.
