It really depends on how much carbon is in the element that you are trying to burn.
>> elements don't contain carbon, carbon is itself an element.
The reason is electron energy levels, different electron shells contain electrons on different energy levels, the lowest being the first shell (which can only contain 2 electrons) - like Hydrogen and Helium have. When combusting with Oxygen, elements create a compound with Oxygen (ex: Zinc burning creates Zinc Oxide), generally between non-metals these bonds are covalent (shared electrons, such as Nitrogen Dioxide), whereas between metals and a non-metal (Oxygen in our case) the bonds are ionic [one element loses it outer electron(s) and the other gains electron(s)], so that both of their outer shells are complete and stable, and their opposite charges holds the compound together.
When electrons change position they either emit of release a photon, this is what causes the Aurora Borealis. With combustion (fire) they are creating chemical bonds, breaking chemical bonds uses up energy (endothermic) and creating chemical bonds releases energy (exothermic). The energy that is released is heat, photons are the carriers of heat and light, and if the heat is high enough it becomes light (hence why bulbs get so hot). So during fire, when electrons change position they release a photon. The higher the energy that the electron has (the further out it's shell is from the atomic nucleus), the higher the frequency of photon (light) that it emits. A deep dark red is the lowest energy level, so Hydrogen burns with a deep dark red flame, because the electron in it's outer shell (which is the one reacting) is also at the lowest energy level possible.

Why do yule logs burn red and green?
Some Yule logs that are available commercially have green and red flames when they burn. The chemicals that cause the colored flames are barium and strontium.
What happens when you burn fresh cut wood in your fireplace?
Wet wood does not burn well. Freshly cut "green" (live) wood can be up to 80 percent water. This water has to be converted to steam and leave the wood before it can burn. While this is happening, the temperature that the wet wood can reach is limited to less than 300 degrees Fahrenheit, dramatically lowering the heat produced by the primary burn. Additionally, the rising steam can significantly extinguish the secondary burn occurring above. Always dry your wood by seasoning it before burning. It usually takes at least six months to dry wood to the desired 20% moisture content for burning, but can often take 12 months or more.
Does all wood burn?
Except for petrified wood (wood that has turned to stone) all wood will burn. Some burns easier than others, some gives off more heat, and some woods are poisonous, and should not be burned- but all wood is capable of burning.
What is another name for a first degree burn?
It is also know as a superficial burn. It is the least severe type of burn.
Is 2x4 good to burn?
yeah its wood it'll burn
Why do some liquids burn while others do not?
The chimicals in some liquids burn others do not.
What element burn?
Boron burns green and because of this is often used in pyrotechnics (Fireworks). I do not know of any others though.
Why does a dry plant burn easier as compared to a green plant?
Green plant matter contains a lot of water. This makes it difficult to burn. While dried plant matter has much less if any moisture and thus burns readily.
Do you need to season ash before burning?
While some people do burn small amounts of green ash, it is better to season it. However, it is one of the few woods that you can burn unseasoned. Though it will be difficult to light, you will use up more wood, and creosote is still an issue. If you do burn it green, burn it along with some seasoned wood.
How do you make a candle burn green?
if you burn copper sulphite
What colour does bronze burn?
Bronze cannons can be a brownish-green color in saltwater. On land it ranges from a white, talc yellow or light green oxidation that brushes off easily.
Has different properties than the elements that make it up?
Water. You can burn oxygen and you can burn hydrogen but you can't burn water.
What color do you get when you burn brass?
Blue and Green depending on the intensity of the heat.
What elements to you get when you burn hydrogen with oxygen?
Hydrogen and oxygen are already elements. You don't get elements as a product. You get water, which is a compound.
What is the substance formed when elements burn in oxygen?
Those would be the "oxides" of the elements burned.
When is green wood safe to burn?
When the green can be felt such as mold although when it is imbedding in the wood that is arsenic and when you burn it the arsenic is transfered into the air.
What element do other elements need to burn?
Oxygen
