Webalkali metal, any of the six chemical elements that make up Group 1 (Ia) of the periodic table—namely, lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). The alkali metals are so called because reaction with water forms alkalies (i.e., strong bases capable of neutralizing acids). Sodium and potassium are the sixth and …
WebJan 15, 2013 · Francium is considered as the most reactive metal; francium has the greatest electropositivity and the lowest electronegativity. Why fluorine is more reactive than oxygen? No, fluorine is... WebFrancium is very scarce and expensive. It is umlikely that anyone has ever reacted the metal with water.

WebAug 15, 2024 · Alkali metals are the chemical elements found in Group 1 of the periodic table. The alkali metals include: lithium, sodium, potassium, rubidium, cesium, and francium. Although often listed in Group 1 due to its electronic configuration, hydrogen is not technically an alkali metal since it rarely exhibits similar behavior. WebAug 17, 2024 · The most reactive metal that has a stable isotope is cesium, which is located directly above francium on the periodic table. The least reactive elements are the noble gases. Within this group, helium is the least reactive element, forming no stable compounds. Metal can have multiple oxidation states and tend to have intermediate reactivity.
WebJul 20, 2024 · Francium (Fr) is quite radioactive, and only small quantities are available for study; so it too is usually omitted. Its properties, however, appear to be similar to those of Cs and the other alkali metals. Chemical Reactions and Compounds The element lithium combines violently and spectacularly with water.
Due to its instability and rarity, there are no commercial applications for francium. It has been used for research purposes in the fields of chemistry and of atomic structure. Its use as a potential diagnostic aid for various cancers has also been explored, but this application has been deemed impractical.
