Bromochlorodifluoromethane (BCF), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F 2 Cl Br. It is used for fire suppression, especially for expensive equipment or items that could be damaged by the residue from other types of extinguishers. [ 1 ]

The template takes parameter number= (atomic number). When this number is >118, the template expands with periods 8 and above, adding the (predicted) elements with atomic number >119. Apart from this 118/119 switching, the parameter is not used as an atomic number. {{Periodic table (32 columns, micro)|number= 119 }} Hydrogen.
Contents. Template:Periodic table legend. This template is a wrapper for a number of legends, each called a theme, used in periodic tables. Examples of themes are: block, state of matter. Each theme can have individual settings for that theme, for example to show "unknown".
Carrier lifetime. A definition in semiconductor physics, carrier lifetime is defined as the average time it takes for a minority carrier to recombine. The process through which this is done is typically known as minority carrier recombination . The energy released due to recombination can be either thermal, thereby heating up the semiconductor ...
Elements. Data pages for elements. Use this template to display a navigation sidebar for the series articles about the periodic table of elements. It includes two parameters, |expanded= and |image= . Parameter |expanded= controls the collapsible lists. By default, all lists are initially collapsed. Use |expanded=all or |1=all to expand all lists:
