WebSep 21, 1999 · lanthanide contraction. pm. valence electron. valence shell. Cesium (Cs), tucked in the lower left hand corner of the table, has the largest known atoms. The atomic radius of Cs is given variously as 273.1 pm [ 1 ], 265 pm [ 2 ], 265.5 pm [ 3] or 260 pm [ 4 ]. Rubidium also has large atoms, but its atomic radius is almost 30 pm less than cesium's. The way the atomic radius varies with increasing atomic number can be explained by the arrangement of electrons in shells of fixed capacity. The shells are generally filled in order of increasing radius, since the negatively charged electrons are attracted by the positively charged protons in the nucleus. As the atomic number increases along each row of the periodic table, the additional electrons go into the same outermost shell; whose radius gradually contracts, due to t…
