Increasing order of Atomic and Ionic Radius: Li ˂ Na ˂ K ˂ Rb ˂ Cs and Li+ ˂ Na+ ˂ K+ ˂ Rb+ ˂ Cs+. Alkali metals can replace hydrogen from any proton donor molecules like alkynes, ammonia, alcohol etc. To have a stable outer shell, Alkali Metals must lose one valence electron. In heavier alkali metal, reaction enthalpy is high such that the metal gets melted and raises to the surface. Alkali metals have one electron in their outer shell, which is loosely bound. Hydrogen is unique in that it is generally placed in Group 1, but it is not a metal. M + (x + y)NH3 → [M(NH3)x]+ + [M(NH3)y]– → MNH2 + ½H2. Alkali metals are named such because they react with water to form alkaline, or basic, solutions. These properties increase from lithium carbonate to carbonate. Lithium differs from other alkali metal it has more covalent nature due to its smallest size, highest ionization energy, strongest electropositive and polarizing nature. Thus they are all univalent electropositive metals. Group 2: Alkaline-earth Metals – Slightly less reactive than alkali metals. The easy loss of this valence electron means that these metals readily form stable cations with a charge of 1+. So the cesium melts into liquid increasing the amount reacting leading to more reaction as a cycle. Elements of group 2 of the periodic table which are metals and has a shiny, silvery-white color are called alkaline earth metals. What element in Period 4 (row) has 5 valence electrons?

Francium (Fr) are all the alkali metals. Sulphates can be reduced by carbon to sulphide. Lithium form imide while other alkalis form amide with liquid ammonia. Alkali metals react vigorously with all the halogens to form solid ionic halides with a definite crystal structure. The Group 1 elements in the periodic table are known as the alkali metals. It was developed in 1927, principally by Arnold Sommerfeld, who combined the classical Drude model with quantum mechanical Fermi–Dirac statistics and hence it is also known as the Drude–Sommerfeld model. For a group number less than 5, the group number is simply the number of valence electrons. They tend to lose the outer shell electron to form cations with charge +1 (monovalent ions). The electron structure, trends and similarities of Group 1 elements, the Alkali Metals. Alkali Metal Properties . SURVEY . However, the main reason why hydrogen (H) is not considered as an alkali metal is that it is mostly found as a gas when the temperature and pressure are normal. Lithium nitrate decomposes into nitrogen dioxide, oxygen and oxide, while the other nitrates of alkali metals yield nitrites and oxygen. Alkali metals or Group 1A elements belong to a common group due to its ns 1 valence electronic configuration. Because they have just one valence electron, group 1 elements are very reactive.
