    as the anion is same and cation are different ... Lattice energy is inversely proportional to size

  • Suman Kumar

    NiF2 will have highest Lattice energy. It is tough to decide between Ni²+ & Cu²+ halide lattice energy. Sometimes Nickel win sometime copper win.

    size of ions - Ca+2 > Mn+2>Cu+2>Ni+2. here Ni+2 ion smallest in size and we know that lattice energy is inversely proportional to size. so NiCl2 have maximum lattice energy

    sir here cu+2 have maximum L.E

    see there is unusual variation in ionic radii among transition metal cations and data also suggest that NiF2 has little bit more L.E than CuF2(3046 for NiF2 n 3042 for CuF2) as you see size of Ni2+ is less than Cu2+

    L.E of transition metal ion in +2 o.s maximum L.E is cuf2+2
