1.4.7 Properties of Ionic Compounds Flashcards
Most ionic, metallic and covalent solids are
crystalline lattices
The ions, atoms or molecules are arranged in a
regular and repeating arrangement
An ionic bond is
an electrostatic force of attraction between a positively charged metal (cation) ion and a negatively charged non-metal (anion) ion
The metal becomes positively charged as it
transfers electrons to the non-metal which then becomes negatively charged
When an ionic compound is formed, the attraction between the ions
happens in all directions
Ionic compounds are arranged in
giant ionic lattices (also called giant ionic structures)
he type of lattice formed depends on the sizes of
the positive and negative ions which are arranged in an alternating fashion
The ionic lattice of MgO and NaCl are cubic:
General ionic lattice which shows the actual packing of the ions:
