As a result of a full shell, the noble gases can be used in conjunction with the electron configuration notation to form the noble gas notation. To do this, the nearest noble gas that precedes the element in question is written first, and then the electron configuration is continued from that point forward. For example, the electron notation of ...
An electrode in which oxidation takes place is called an anode while in that which reduction takes place is called cathode. This applies for both electrolytic and electrochemical cells, though the charge on them reverses. The red cat and an ox mnemonics are useful to remember the same. Red cat: Reduction at cathode; An ox: Anode for oxidation. [28]
"halogen" and "noble gas" are used to refer to the entirety of groups 17 and 18, per a 2016 IUPAC report about naming new elements [4] Some sources focusing on superheavy elements may not consider tennessine (Ts) to be a halogen, or oganesson (Og) to be a noble gas, as their predicted chemistry is generally supposed to be quite different from ...
The anode sludges contain the selenides and tellurides of the noble metals in compounds with the formula M 2 Se or M 2 Te (M = Cu, Ag, Au). At temperatures of 500 °C the anode sludges are roasted with sodium carbonate under air. The metal ions are reduced to the metals, while the telluride is converted to sodium tellurite. [38]

These are notations for describing states of singly excited atoms, especially noble gas atoms. Racah notation is basically a combination of LS or Russell–Saunders coupling and J 1 L 2 coupling. LS coupling is for a parent ion and J 1 L 2 coupling is for a coupling of the parent ion and the excited electron. The parent ion is an unexcited part ...
Neon is the second-lightest noble gas, after helium. Like other noble gases, neon is colorless and odorless. It glows reddish-orange in a vacuum discharge tube. It has over 40 times the refrigerating capacity (per unit volume) of liquid helium and three times that of liquid hydrogen. [3]
Ng: any noble gas (Rg is sometimes used, but that is also used for the element roentgenium: see above) Nu: any nucleophile; R: any unspecified radical not important to the discussion; St: steel (occasionally used) X: any halogen (or sometimes pseudohalogen)
