What element in the following groups has the lowest atomic mass alkali metal alkaline earth metal halogen noble gas?
Among the groups mentioned, lithium (Li) is the alkali metal with the lowest atomic mass, at approximately 6.94 u. In the alkaline earth metals, beryllium (Be) has the lowest atomic mass at about 9.01 u. For halogens, fluorine (F) is the lightest, with an atomic mass of around 19.00 u, and in the noble gases, helium (He) has the lowest atomic mass, approximately 4.00 u. Thus, helium has the lowest atomic mass overall among these groups.
