Part B Explain the relationship between the number of valence electrons and the resulting chemistry of alkali metals. Reset Help 1A The alkali metals (group ) have one valence electron and are among the 2A reactive metals because their outer electron configuration (ns) is one electron the ns electron, obtaining a noble beyond a noble gas configuration. They react to gas configuration. This is why the group 1A metals tend to form cations most gain least lose Submit My Answers Give Un Part C This question will be shown after you complete pre Part D
