Alkali Metal Definition (Chemistry) - ThoughtCo
WebThe alkali metals are so reactive, due to a number of factors. Their low first ionization energy, combined with the fact they have just 1 electron to donate to get to a stable full shell state, makes them so reactive – even more so as their atomic radium gets larger. WebDec 12, 2024 · The reactivity of alkali metals increases from the top to the bottom of the group, so lithium (Li) is the least reactive alkali metal and francium (Fr) is the most reactive. Because alkali metals are so reactive, they are found in nature only in combination with other elements. incydent bhp definicja
