Impurities in a metal can significantly affect its melting point. Pure metals usually have a higher melting point, while metal alloys containing impurities tend to have a lower melting point. This is because impurity atoms may disrupt the regularity of the metal lattice, thereby reducing the binding force between the atoms.

Therefore melting and boiling points of alkali metals are less than melting and boiling points of alkali earth metals. Why beryllium have high melting point and boiling point than other member of group two? Beryllium is the smallest size atom of the group 2 elements. So its ionic lattice is more stronger than other alkaline earth metals.

The arrangement of atoms in a crystalline lattice or amorphous structure also plays a critical role. Crystalline solids, with orderly arrangements of atoms, require more energy to disrupt, leading to higher melting points. In contrast, amorphous solids, such as glass, do not have a defined melting point but rather soften over a temperature range.
