Atoms of each of these elements … WebReactions of Alkaline Earth Metals All the alkaline earth metals have two electrons in their valence shell, so they lose two electrons to form cations with a 2+ charge. Most of the chemistry has been observed only for the first five members of the group; the chemistry of radium is not well established due to its radioactivity. In chemical terms ...
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 ). WebChemical properties. Since the alkali metals are the most electropositive (the least electronegative) of elements, they react with a great variety of nonmetals.
