Web14 de set. de 2024 · Common periodic trends include those in ionization energy, atomic radius, and electron affinity. One such trend is closely linked to atomic radii -- ionic radii. Neutral atoms tend to increase in size down a group and decrease across a period. When a neutral atom gains or loses an electron, creating an anion or cation, the atom's radius ... Web3 de fev. de 2024 · 6.10A: Ionic Radii. In a crystal lattice, the ionic radius is a measure of the size of the atom's ion. 6 When formed, ionic atoms change in size with respect to their orginal atom. Cation radii will decrease and the anion radii will increase in size compared to their neutral atoms. WebThe two main factors affecting lattice enthalpy are the charges on the ions and the ionic radii (which affects the distance between the ions). The charges on the ions.
