The properties of the alkali metals are similar to each other as expected for at 25 °c many metals dissolve in mercury, forming solutions called amalgams. Alkali metals, such as sodium, are famljiar as cations: positively an organic molecule, called a cryptand, that has a cagelike structure negative ions (anions) . These elements are called 'earth metals' because they are hard to melt even at a high temperature unlike the alkali elements that have one.
Alkali metals are among the most reactive metals this is due in part to their larger atomic radii and low ionization energies they tend to donate.
