This userbox has eight parameters. Their functions are:

  1. Border colour. Leaving this parameter blank gives a black border.
  2. Phase - insert "Solid", "Liquid", "Gas" or "UnknownPhase" for the element's phase at 25°C = 77°F = 298°K and 1 atm. Leaving this parameter blank has the same result as "Solid". In case this is not known to the template user, here is the complete list:
  3. The element's atomic number - see list of elements for information.
  4. The element's chemical symbol - see list of elements for information.
  5. The element's atomic weight - see list of elements for information.
  6. The colour showing the element's chemical series. See the section below.
  7. Name of the element - see list of elements for information. Please begin it with a lowercase letter, as element names are not capitalized in English (unless at the beginning of a sentence).
  8. Background of the text in the userbox (not the ID). If left blank, the background will be transparent.

Colour codes

edit
chemical series color code description
alkali metals #ff6666 Very reactive and therefore dangerous = red.
alkaline earth metals #ffdead Nice earthy color = easy to remember.
lanthanides #ffbfff The current color was chosen arbitrarily.
actinides #ff99cc The current color was chosen arbitrarily.
transition metals #ffc0c0 Another shade of gray (or even silver) would work here. But that would make the table a bit drab and the colors of the metals and transitions metals too similar.
poor metals #cccccc True metals are closest in color to gray.
metalloids #cccc99 Intermediate color between above and below.
nonmetals #a0ffa0 Elements most essential to life. Most life on Earth (measured by biomass) is photosynthetic and chlorophyll is green.
halogens #ffff99 Fluorine gas is yellowish as are many precipitates of halogens.
noble gases #c0ffff Non-reactive for practical purposes. Cyan is soft and soothing (it is also the opposite of red).
unknown chemical properties #e8e8e8 This shade of gray usually signifies "unknown".
undiscovered #ffffff White usually signifies "unknown", it being a blank space where the element symbol is floating.
superactinides #f4f4c6 The current color was chosen arbitrarily.

Example

edit

{{User:UBX/Element||UnknownPhase|104|Rf|[261]|#ffc0c0|rutherfordium|}}

will produce:

104
Rf
[261]
This user's favourite element is rutherfordium.




If you want further stylizing, you can add the other parameters:

{{User:UBX/Element|#6cacde|UnknownPhase|104|Rf|[261]|#ffc0c0|rutherfordium|#fc86f6}}

which will produce:

104
Rf
[261]
This user's favourite element is rutherfordium.
