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 ). WebThe reactivity of Group 1 elements increases as you go down the group because: the atoms get larger the outer electron gets further from the nucleus the attraction between the nucleus and outer...
