Here are some tasks awaiting attention:

Q-carbon[edit]

I propose that Q-Carbon is added to the list of carbon's solid states. reference [1]

With sulfide? what state?[edit]

Quote:

with sulfur to form carbon disulfide and with steam in the coal-gas reaction:
C(s) + H2O(g) → CO(g) + H2(g).

There is no sulfur in this reaction. Does anyone know what has happened here?

Why are we using (s) and (g) here? This is not interesting in a chemical reaction.

control the carbon content of steel:

Fe3O4 + 4 C(s) → 3 Fe(s) + 4 CO(g)

In this reaction, iron is molten, not solid (s). Fe3O4 does not have (s). I suggest we just drop these phase (state) designations in these equations. This is the first in about 30 pages where they appear. Consensus?

External links modified[edit]

Hello fellow Wikipedians,

I have just modified one external link on Carbon. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

Typo: "Isotopess"[edit]

Third sentence: Three -"isotopess"- occur naturally, 12C and 13C being stable, while 14C is a radioactive isotope, decaying with a half-life of about 5,730 years. ASteveMt (talk) 17:26, 7 January 2017 (UTC)

misprint[edit]

you've got a misprint in the infobox of this "good article". The standard atomic weight of carbon is 12.0096 to 12.0116 not 12.096 to 12.116
