The alkali metals are potent reductants whose chemistry is largely that of ionic compounds containing the M+ ion. Alkali metals have only a weak tendency to form complexes with simple Lewis bases. …
Alkali metals are powerful reductants and so do not exist as the free metal in the relatively oxidizing environment at the earth's surface. As a result they are commonly found as the +1 cations in a variety of minerals like rock salt (halite, NaCl) and natron (Na 2 CO 3 ·10H 2 O).
The alkali metals react with halogens (group 17) to form ionic halides; the heavier chalcogens (group 16) to produce metal chalcogenides; and oxygen to form compounds, whose stoichiometry depends on the size of the metal atom.
The Group 1 metals have a particular name: the alkali metals. This is due to the formation of alkali (basic) solutions upon their reaction with water. Table \(\PageIndex{3}\).1 lists the derivation of the names of the alkali metals.
17 wrz 2024 · Alkali metal, any of the six elements of Group 1 (Ia) of the periodic table—lithium, sodium, potassium, rubidium, cesium, and francium. The alkali metals are so called because reaction with water forms alkalies (i.e., strong bases capable of neutralizing acids).
The metals in Group I of the periodic table are called the alkali metals. They are: lithium (Li) sodium (Na) potassium (K) rubidium (Rb) caesium (Cs) francium (Fr) Properties of alkali metals: The alkali metals have the high thermal and electrical conductivity, lustrous, ductile, and malleable that are characteristic of metals.
