The carbon formula is simply C.
Since carbon is an element, it exists as a single type of atom. Therefore, its molecular formula is represented by its element symbol, which is "C". It doesn't combine with other elements to form a molecule in its elemental state; it simply is carbon. Think of it like this:
- Element: Carbon
- Symbol: C
- Formula: C
It's important to differentiate this from compounds containing carbon, such as carbon dioxide (CO₂) or methane (CH₄), where carbon atoms are bonded to other elements. The "carbon formula" refers specifically to pure, elemental carbon.
