What group can alkali metals pair with in a 1:1 ratio? A. the oxygen group B. halogens C. alkaline earthmetals D. transition metals

lkali metals can pair with halogens in a 1:1 ratio. This is because alkali metals have one valence electron that they readily lose to form a +1 ion, while halogens have seven valence electrons and need one more to complete their octet, forming a -1 ion. The resulting compound is neutral and stable.<br /><br />So the correct answer is:<br /><br />B. halogens
