Yes, there can be non carbon based life forms; although none yet have been discovered; there is much speculation about the possibility of silicon based life forms due to certain similarities to carbon at the atomic level.
Different non-crystalline forms of carbon include amorphous carbon, activated carbon, carbon black, and carbon nanotubes. These forms have irregular atomic structures and lack long-range order typical of crystalline forms like diamond or graphite.
No. There would be no sun or stars without hydrogen and so none of the heavier elements would be formed. All life forms on earth are based on carbon - a non-metal. Most of them conatin organic compounds which are mainly based on non-metallic compounds. The need to breath oxygen (a non metal).
The nonmetal carbon forms the basis of life. The carbon compounds made by living things are said to be organic. Organic compounds not only contain carbon, but also hydrogen. The most common elements found in living things are carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur. All of these elements combine in various ways to produce thousands of organic compounds. The study of the chemistry of living things is called biochemistry.
Carbon forms calcium carbide and carbon tetrachloride.
The symbol C represents carbon on the periodic table. Carbon is a non-metal element with the atomic number 6. It is a key building block of life and is found in various forms, such as graphite and diamonds.
While carbon-based life forms are the most common on Earth, it is theoretically possible for non carbon-based life forms to exist. However, there is currently no evidence of such life forms on our planet.
As of now, no non carbon-based life forms have been found on Earth. All known life on Earth is carbon-based.
There is limited evidence to support the possibility of non-carbon based life on Earth. Some scientists have suggested that alternative biochemistries, such as silicon-based life forms, could potentially exist in extreme environments where carbon-based life may not survive. However, no definitive proof of non-carbon based life on Earth has been found.
After discovering non-carbon based life-forms at the deepest depths of our own planets' oceans, we are faced with the possibilty that life could exist on other planets even though they might or do possess atmospheres unsuited to the conventional carbon-based forms of life as we know them here on earth

....Don't think that there are any non-carbon life forms that we know of. The only other possibility for life to exist without the use of carbon is probably in Silicon. Silicon is similar to Carbon in that it has an equal number of bonding sites- that is, areas where electrons may be shared between molecules. The problem, however, lies in the size of the atom/molecule/whatever you want to refer to it as. Silicon is larger than carbon. As atoms grow larger, their nuclei grow more positive, and therefore more repellent. This would prevent Silicon from forming the tremendous chains of molecules that Carbon does so easily. The basic answer to your question is, Nothing. There are no living things made of silicon.
Carbon can be organic and non organic.
For something to be considered living, it usually needs to exhibit certain characteristics such as metabolism, growth, reproduction, response to stimuli, and homeostasis. While carbon-based molecules are common in living organisms on Earth, the definition of life could be broader and include non-carbon-based life forms. A large self-replicating molecule alone may not be enough to qualify as a living organism without displaying other essential life processes.
