The farther to the left and toward the bottom of the periodic table, the lower the electronegativity, and the larger the atomic radius. Calcium has a large atomic radius in comparison to elements in it's own period. What are you comparing calcium too? Calcium does have a large radius but not the largest, the largest is Cesium.
