It is defined as one-half of the distance between the two adjacent atoms in the crystal lattice. Ionic radius means the size of the ions. It may be defined as the effective distance from the nucleus of the ion to the point to which it has an influence in the ionic bond. WebIf the ionic radii of K + and F − are about 1.34 A˚ each, then the expected values of atomic radii of K and F should be 2.31 and 0.64 A˚ respectively. Cations are always shorter than their parent atom, anions are always larger. Thus radii of K + will be more than 1.34 and that of F − will be less than 1.34. Hence, option B is correct. cia challenge exam philippines

WebThe ionic radii of the lanthanides decrease from 103 pm (La 3+) to 86 pm (Lu 3+) in the lanthanide series, as electrons are added to the 4f shell. This first f shell is inside the full 5s and 5p shells (as well as the 6s shell in the neutral atom); the 4f shell is well-localized near the atomic nucleus and has little effect on chemical bonding.
