A bond graph in solid-state chemistry is a chemical formula of an extended structure, in which direct bonding connectivities are shown. An example is the AuORb 3 perovskite, the unit cell of which is drawn on the left and the bond graph (with added numerical values) on the right:
This table lists in its first column the initial digits of the country code shared by each country in each row, which is arranged in columns for the last digit. When three-digit codes share a common leading pair, the shared prefix is marked by an arrow, ( ↙ ) pointing down and left to the three-digit codes.
The following is a list of RAL Classic colours [1] from the RAL colour standard. The visual samples are approximate and informative only. The visual samples are approximate and informative only. RAL Classic
The ion transport system moves potassium across the cell membrane using two mechanisms. One is active and pumps sodium out of, and potassium into, the cell. The other is passive and allows potassium to leak out of the cell. Potassium and sodium cations influence fluid distribution between intracellular and extracellular compartments by osmotic ...
For states, the "Status" column in the table below includes a link to a list of the counties (boroughs and census areas in Alaska; parishes in Louisiana) for that state including the county codes as defined in FIPS PUB 6-4. The listings of counties for other areas are set out at the end of this article.
One LiMnO 2 cell can replace two alkaline or silver-oxide cells. IEC designation numbers indicate the physical dimensions of the cylindrical cell. Cells less than one centimeter in height are assigned four-digit numbers, where the first two digits are the diameter in millimeters, while the last two digits are the height in tenths of millimeters.
Here [Ne] refers to the core electrons which are the same as for the element neon (Ne), the last noble gas before phosphorus in the periodic table. The valence electrons (here 3s 2 3p 3 ) are written explicitly for all atoms.
Table notes [*] Codes that are not cut numbers, or are not numbers, are shaded grey in the table. [†] There are no distinct cut-number codes for 4 or 6, since cut numbers come from reducing multiple dahs in the standard Morse number codes to only one dah, but keeping all the dits as-is. [‡]
