Individual Elements in Group 5A. Rubidium has 211, Potassium 196, and Sodium 154. Relevance. Elements from the halogen group including F, Cl, Br have pretty high electronegativities. You probably meant here “which elements are the largest atoms”, meaning which elements have the largest atomic radius. The halogens are located in Group VIIA of the periodic table. Ba is in group 2A and in row 6 (farthest “down” a group) and is the largest of the atoms. What happens to the atomic size of the elements as one goes from the top to the bottom of a group? We usually find it in air, polymers, organic compounds, carbonates etc. Most elements on the left side of the periodic table are A. nonmetals B. metals 14. That means that since the lower the element is in a group, the larger the atomic radius will be. The radii of group 14 elements are lesser than that of group 13 elements.
