Group 2 metals have higher MPs that Group 1, although they will be on the same period. The stronger metallic bonds e.g Mg in group 2 are due to the fact Mg forms 2+ ions and will contribute 2 electrons per atom to the delocalised pool of electrons. Both factors result in stronger metallic bonds, a greater energy to overcome bonds so a higher MP.
There are three types of strong chemical bonds: ionic, covalent and metallic. For ionic bonding the particles are oppositely charged ions.For covalent bonding the particles are atoms which share pairs of electrons.For metallic bonding the particles are atoms which share delocalised electrons.. Ionic bonding occurs in compounds formed from metals combined with non-metals.
