Lattice Energy Nasıl Hesaplanır?
learn.whatIsHeading
Lattice energy is the energy released when gaseous ions combine to form a crystalline ionic solid (or equivalently, the energy required to separate the solid into gaseous ions). It measures the strength of ionic bonding.
Adım Adım Kılavuz
- 1Proportional to |z+||z−|/r (Coulomb's law)
- 2|z| = ionic charges · r = sum of ionic radii
- 3Higher charges and smaller ions → larger lattice energy
- 4Measured experimentally via Born-Haber cycle

Giriş
NaCl vs MgO comparison
Sonuç
NaCl ≈ −787 kJ/mol · MgO ≈ −3795 kJ/mol
MgO has 2+ and 2− ions → much larger lattice energy
