alkali metals, metals found in Group 1 of the periodic table. Compared to other metals they are soft and have low melting points and densities. Alkali metals are powerful reducing agents and form univalent compounds. All react violently with water,
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 neutralizin

Alkali metals are the six elements that comprise Group I in the Periodic Table: lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). Especially when dissolved in water, these elements form strong bases (alkalis) capable of reacting with and ...
Alkali metals are elements that belong to Group 1(a) of the periodic table, this includes Lithium, Sodium, Potassium, Rubidium, Cesium and Francium. What are the main properties of alkali metals? Like all metals alkali metals are shiny in appearance and good conductors of electricity; however,...
Ans.Alkali metals have a single electron on their outer shell, while all the noble gases (the Group 8 elements in the periodic table including helium, neon, argon) have a full valence band with no unpaired electron to cause a reaction with other molecules[15]. ...
