Ionic bonding
1 the electrostatic attraction between cation and anion after electron transfer.
2 Combined atoms which have a large difference of electronegativities
2.1 Metal loses electron(s) : cation. Non-metal gains electron(s) : anion.
3 Ionic compound
3.1 Writing formula by write cation followed by anion and balance the charge.
3.2 Naming compounds by name cation followed by anion ended with -ide. If the compounds consists polyatomic ions, use the name of polyatomic ions
3.3 Cation + Anion
3.3.1 can be polyatomic ions
3.4 Ionic radius
3.4.1 Cation is smaller than its corresponding atom.
3.4.2 Anion is larger than its corresponding atom.
4 Born-Haber Cycle
4.1 Energies involve in forming ionic compounds.
4.1.1 Ionization energy : metal loses electron(s). (step 3)
4.1.2 Electron Affinity : non-metal gains electron(s). (step 4)
4.1.3 Lattice energy : energy released from combination of cation and anion. (step 5)
4.1.3.1 Definition: Lattice energy is the energy needed to separate an ionic solid into isolated ions in the gas phase.
4.1.3.2 Lattice energy depends on size and charge of ions.
4.1.3.3 Lattice energy determines the strength of ionic bonds and solubility of ionic compounds.
