WebbFor example, the atomic radius of the metal zirconium, Zr (a period-5 transition element), is 155 pm (empirical value) and that of hafnium, Hf (the corresponding period-6 element), is 159 pm. The ionic radius of Zr 4+ is 84 pm and that of Hf 4+ is 83 pm. The radii are very similar even though the number of electrons increases from 40 to 72 and the atomic … WebbSo analyzing the given pair: a. As shown below, Ge has greater atomic radii than Si. Therefore, their atomic radii are not similar at all. b. Tracing across the period we can …
