What causes the changes in ionisation energy across period 2 elements?
Which of the options below provides a reason why the covalent radius of hafnium (1.44 Å) is less than that of zirconium (1.45 Å), even though the element above it in the periodic table? A. Between Zr and Hf lies the 4d10 configuration due to the transition metals. This leads to much greater Z* because the d electrons are so poor at shielding. Thus Hf is smaller than expected for an element in a higher shell than Zr, called the Scandide contraction. B. Hf being below Zr suggests that it will have a smaller atomic radius because the trend shows a decrease going down a group. C. Hf is below Zr and has a smaller ionisation energy, electron affinity and electronegativity compared to Zr. This reduces its atomic radius, thus leading to it having a smaller atomic radius compared to that of Zr. D. Between Zr and Hf lies the 4f14 configuration due to the Lanthanides. This leads to much greater Z* because the f electrons are so poor at shielding. Thus Hf is smaller than expected for an element in…
