I will review, but I might miss a few things and mistakes (especially the references). I'll divide the review into sections, and write for each one. At the end of the review page I will put the criteria for the good article.

Charecteristics

• "Carbon also has the highest melting and sublimation point of all elements. At atmospheric pressure it has no melting point as its triple point is at 10.8 ± 0.2 MPa and 4600 ± 300 K,[2][3] so it sublimates at about 3900 K.[15][16]" It says that it has the highest melting point of all of the elements, then contradicts itself by saying it has no melting point. Anything to reword, mabye putting its melting point under a certain pressure? (unless it will still sublime, them mabye put that it doesn't have one because it sublimes)

• Mabye put the temperatures in degrees celsius too (and farenheight)? Just for people who might not know the kelvin scale or don't understad a given temperature's degree of heat or coolness?(?) in kelvin like not knowing that 100 K is like way below freezing temperatures.

• "Although thermodynamically prone to oxidation, carbon resists oxidation more effectively than elements such as iron and copper that are weaker reducing agents at room temperature." source? and just asking, why are its properties being compared so much to metals even though it is a nonmetal? The difference between metals and nonmetals is very great already such as brittleness, refractivity, flexability, tendance of different states of matter...

• from the text "It does not react with sulfuric acid..." to the text "...C(s) + H2O(g) → CO(g) + H2(g)." in the third para. Put a source for its reactions with the compounds and the substances with which it doesn't react.

That's all for now. I'll be back soon with more remarks. --Geo7777 (talk) 15:00, 30 June 2011 (UTC)

Ok, I'm back, I'm continuing with where I left off.

allotropes

Just fine.

Occurrence

Ok, except for two things:

• Coal is a significant commercial source of mineral carbon; anthracite containing 92–98% carbon[39] and the largest source (4,000 Gt, or 80% of coal, gas and oil reserves) of carbon in a form suitable for use as fuel.[40] unclear. Reword?

• in the fifth, sixth, and seventh paragraph, can you put a source for each of them?

The rest is fine.

Isotopes

Perfect.

Formation in Stars

good, but fix the "citation needed" template in the last paragraph.

done for this time :)--Geo7777 (talk) 18:12, 2 July 2011 (UTC)

Carbon Cycle

Nice

Compounds

Organic Compounds

The wording and prose is fine, but the one thing that directly caught my sight was that there was no sources for all of the papagraphs. please fix them so they can be at least one ref. per para.

Inorganic Compounds

Awesome

I'll be back for more... :) --Geo7777 (talk) 18:12, 2 July 2011 (UTC)

I'm back, so i will pick up where i left off.

Organometallic compounds

Good.

History and etymology

Very good.

Production

Graphite

good, even though at first it seemed that there was only one ref. until i looked through the ref. and saw it had all of the info placed.

Diamond

A good subsection.

the rest of the paragraphs, after a thorough look through them, are of good article quality. Now I will check the lead against the criterion 1b. Geo7777 (talk) 04:47, 6 July 2011 (UTC)

1. Is it reasonably well written?

   A. Prose quality:

   B. MoS compliance for lead, layout, words to watch, fiction, and lists:

2. Is it factually accurate and verifiable?

   A. References to sources:

   B. Citation of reliable sources where necessary:

   C. No original research:

3. Is it broad in its coverage?

   A. Major aspects:

   B. Focused:

4. Is it neutral?

   Fair representation without bias:

5. Is it stable?

   No edit wars, etc:

6. Does it contain images to illustrate the topic?

   A. Images are copyright tagged, and non-free images have fair use rationales:

   B. Images are provided where possible and appropriate, with suitable captions:

7. Overall:

   Pass or Fail:

Congratulations, Carbon is now a Good article!!
