Higher melting point sodium
WebWhy dose sodium oxide have a high melting point? Sodium oxide has a formula of Na 2 O. Since sodium is a metal and oxygen is a non metal, sodium oxide is an ionic … WebThree metallic structures. Sodium, magnesium and aluminium all have metallic structures, which accounts for their electrical conductivity and relatively high melting and boiling points. Melting and boiling points rise across the three metals because of the increasing number of electrons which each atom can contribute to the delocalised "sea of ...
