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 some Ionic elements. A more purely Ionic mode to be seen on the Athenian Acropolis is exemplified in the Erechtheum.
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
It is a depiction of the periodic law, which states that when the elements are arranged in order of their atomic numbers an approximate recurrence of their properties is evident. The table is divided into four roughly rectangular areas called blocks. Elements in the same group tend to show similar chemical characteristics.
The Temple of Olympian Zeus, Athens, (174 BC–132 AD), with the Parthenon (447–432 BC) in the background. This list of ancient Greek temples covers temples built by the Hellenic people from the 6th century BC until the 2nd century AD on mainland Greece and in Hellenic towns in the Aegean Islands, Asia Minor, Sicily and Italy ("Magna Graecia"), wherever there were Greek colonies, and the ...

There are currently seven complete periods in the periodic table, comprising the 118 known elements. Any new elements will be placed into an eighth period; see extended periodic table. The elements are colour-coded below by their block: red for the s-block, yellow for the p-block, blue for the d-block, and green for the f-block.
He reproduced the orbital order of Fricke et al., and proposed a refinement of their table by formally assigning slots to elements 121–164 based on ionic configurations. [13] In order to bookkeep the electrons, Pyykkö places some elements out of order: thus 139 and 140 are placed in groups 13 and 14 to reflect that the 8p 1/2 shell needs to ...
However, in 2004, the German archaeologist Hans Lohmann, surveying the peninsula of Mt. Mycale, discovered another archaeological site high in the mountains, a settlement and an archaic temple (about mid 6th century BC) of the Ionic order. In the summer of 2005, the temple was excavated in cooperation with the Museum of Aydın. Lohmann assumes ...
