The red pigment vermilion is obtained by grinding natural cinnabar or synthetic mercuric sulfide. Mercury occurs in deposits throughout the world mostly as cinnabar ( mercuric sulfide). A heavy, silvery d-block element, mercury is the only metallic element that is known to be liquid at standard temperature and pressure the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature. It is also known as quicksilver and was formerly named hydrargyrum ( / h aɪ ˈ d r ɑːr dʒ ər ə m/ hy- DRAR-jər-əm) from the Greek words hydro (water) and argyros (silver).
CHEMICAL SERIES PERIODIC TABLE MANUAL
Another version of the periodic table can be found in the Starfleet Medical Reference Manual which is devoid of the "in-jokes" found on the Next Generation version.Mercury is a chemical element with the symbol Hg and atomic number 80. It is unknown if this table was also labeled with different elements than those seen in "Rascals". However, in at least one case, in the episode " Cardassians" (see image on right), the table had a different color code. The table from "Rascals" was later used for the classroom scenes on Star Trek: Deep Space Nine. This can be seen with the element poi, the heaviest element, and that its physical atomic size is much smaller than that of the element hawkeye, which is much lighter in terms of atomic weight. It is also interesting to note that the size of the atom itself (as seen in the okudagram of the Table of Elements) does not affect the atomic weight. Elements are also sorted by "atomic weight," and the atomic weights of the known elements differ from their actual atomic weights. It contains many in-jokes and errors, and is missing several key elements. The Table of Elements on station Deep Space 9 In 3189, Ensign Sylvia Tilly discovered minerals at a settlement on a planet which were not on the elemental table. ( TAS: " One of Our Planets Is Missing")Ī Table of Elements was seen in a classroom aboard the USS Enterprise-D ( TNG: " Rascals") and also in the classroom on Deep Space 9's Promenade.
In 2269, Spock stated that the matter- energy cloud had " elements not known in our periodic tables". On October 23, 2032, Lieutenant John Kelly recorded that after analyzing the contents of a graviton ellipse it would be necessary to make room on the periodic table. ( TAS: " One of Our Planets Is Missing") Using the table, many elements shared a common atomic weight or symbol, and some even have multiple atomic weights or symbols and are listed twice.īenny Russell had a periodic table on the wall of his kitchen in 1953. Multiple periodic tables were known to the Federation, though elements unknown to any of them still existed. A periodic table, also known as Table of Elements or elemental table, was a means of grouping chemical elements.
