The alkali metals tend to form +1 cations. Cation formation is favored by the relatively low ionization energies of the free metal (which makes it easier to form the cation) and the high solvation energy of their cations (which indicates that the cation is thermodynamically stabilized in solution).

- 20.4: The Alkali Metals (Group 1)
General Properties of the Alkali Metals. Various properties of the group 1 elements are summarized in Table \(\PageIndex{1}\). In keeping with overall periodic trends, the atomic and ionic radii increase smoothly from Li to Cs, and the first ionization energies decrease as the atoms become larger.
27 sty 2016 · The lone outer shell electrons leads the alkali metal elements to share several common properties: The one outer electron is easily lost, forming the univalent (1+) cation (e.g., Na + ). Alkali metals are typically less dense than other metals.
Scroll down to learn about the uses of alkali metals. Alkali metals or Group 1A elements belong to a common group due to its ns 1 valence electronic configuration. The properties of an element have periodic dependence on its atomic number but not on atomic weight.
