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 ]
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 ...
The most common are Celtic sea salt, Fleur de Sel from the French sea, and Hawaiian sea salt. Sea salt is less refined than conventional table salt, with retaining traces of minerals and ...

To change this template's initial visibility, the |state= parameter may be used: {{Periodic table (boiling point)|state= collapsed }} will show the template collapsed, i.e. hidden apart from its title bar. {{Periodic table (boiling point)|state= expanded }} will show the template expanded, i.e. fully visible.
Left-step periodic table (by Charles Janet) This form of periodic table is congruent with the order in which electron shells are ideally filled according to the Madelung rule, as shown in the accompanying sequence in the left margin (read from top to bottom, left to right). The experimentally determined ground-state electron configurations of ...
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.
