Ionic order Ionian dialect was spoken. The Ionic order column was being practiced in mainland Greece in the 5th century BC. It was most popular in the Archaic Period (750–480 BC) in Ionia. The first of the great Ionic temples was the Temple of Hera on Samos, built about 570–560 BC by the architect Rhoikos. It stood for only a decade before it was leveled by an earthquake. A longer-lasting 6th century Ionic temple was the Temple of Artemis at Ephesus, one of the Seven Wonders of the Ancient World. The Parthenon, although it conforms mainly to the Doric order, also has
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
