The alkali metals consist of the chemical elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). Together with hydrogen they constitute group 1, which lies in the s-block of the periodic table. All alkali metals have their outermost electron in an s-orbital: this shared electron configuration results in their having very similar characteristic properties. Indee
READ MORE4 · In chemistry, an alkali (/ ˈ æ l k ə l aɪ /; from Arabic: القلوي, romanized: al-qaly, lit. ''ashes of the saltwort'') is a basic, ionic salt of an alkali metal or an alkaline earth metal.An alkali can also be defined as a base that dissolves in water.A solution of a soluble base has a pH greater than 7.0. The adjective alkaline, and less often, alkalescent, is commonly

READ MOREAlkali metal - Properties, Reactivity, Uses: The alkali metals have the high thermal and electrical conductivity, lustre, ductility, and malleability that are characteristic of metals. Each alkali metal atom has a single electron in its outermost shell. This valence electron is much more weakly bound than those in inner shells.
