Greco-Roman world and Latin. "Greco-Roman" architecture is the architecture of the Roman world that followed the principles and style established in ancient Greece. The most representative building of that era was the temple. Other prominent structures that represented the style included government buildings, like the Roman Senate, and cultural structures, like the Colosseum. The three primary styles of column design used in temples in classical Greece were Doric, Ionic and Corinthian. Some examples of Doric architecture are the Parthenon and the Temple of Hephaestus in Athens, while the Erechtheum, which is located right next to the Parthenon is Ionic. The Romans made
Ionic compound and negative ions must be maintained. Instead the material undergoes fracture via cleavage. As the temperature is elevated (usually close to the melting point) a ductile–brittle transition occurs, and plastic flow becomes possible by the motion of dislocations. The compressibility of an ionic compound is strongly determined by its structure, and in particular the coordination number. For example, halides with the caesium chloride structure (coordination number 8) are less compressible than those with the sodium chloride structure (coordination number 6), and less again than those with a coordination number of 4. When ionic compounds dissolve, the individual ions dissociate and
