Web75. Use principles of atomic structure to answer each of the following: 1. (a) The radius of the Ca atom is 197 pm; the radius of the Ca 2+ ion is 99 pm. Account for the difference. (b) The lattice energy of CaO ( s) is –3460 kJ/mol; the lattice energy of K 2 O is –2240 kJ/mol. Account for the difference. WebThe geometrical arrangement will vary according to the number and type of ligands bonded to the metal centre, and to the coordination preference of the central atom, typically a metal in a coordination complex. The number of atoms bonded, (i.e. the number of σ-bonds between central atom and ligands) is termed the coordination number .
