What is the largest element in the alkali metal?
No. In fact lithium, one of the alkali metals, is the lightest metal. In terms of molecular mass the heaviest metals are the actinides. In terms of density the densest metals are osmium and iridium.
Which element has a greater atomic mass A or B?
Element A has a greater atomic mass than element B if the atomic mass value of A is higher. The atomic mass represents the average mass of an element’s isotopes based on their abundance in nature.
What is the atomic mass of francium?
The atomic mass of francium is approximately 223. It is a highly radioactive element and the heaviest known alkali metal.
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.
