Group of elements in the periodic table of
the elements - group I or Ia: lithium (Li),
sodium (Na), potassium (K), rubidium (Rb),
caesium (Cs), and francium (Fr). In general,
the elements of this group are reactive,
soft, low-melting-point metals. Because of
their reactivity they are only found as
compounds in nature, and are used as
chemical reactants rather than as structural
metals.
