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 for high-temperature solid-state synthesis. Many metals are geologically most abundant as ionic compounds within ores. To obtain the elemental materials, these ores are processed by smelting or electrolysis, in which redox reactions occur (often with a reducing agent such as carbon) such that the metal ions gain electrons to become neutral atoms. According to the nomenclature recommended by IUPAC, ionic compounds are named according to their composition, not their structure. In the most simple case of a binary ionic compound with no possible ambiguity about the charges and thus the stoichiometry, the common name is written using two words. The
