yes it does. the chemical behavior of a radioactive isotope is essentially the same as that of the stable isotopes of an element. When you have the addition of a small quanity of radioactive isotope, it becomes a tracer, which traces molecular changes. (look up the Melvin Calvin experiment for more help)
Yes.
NO --------------- I know of no pure carbon forms that are explosive (maybe there is some strained crystal structures). Though carbon could be explosive if a fine dispersion of it in air was ignited. Also acetylene and particularly its silver salt is very explosive Ag-CΞC-Ag. Even though this isn't purely carbon based, the energy is stored in the tripple bond between the carbon atoms.
Yes. A compound is a substance made of atoms that are chemically bonded.
Plants obtain the carbon that they need in the form of carbon dioxide from the air, not from the soil. Even if carbon were added to fertiliser plants would be unable to make use of it.
I know that RadioActive gives the MOST energy even if 1 gram is burned!
Carboxylic acids with odd number carbon atoms are packed in crystals less efficiently than those that have even numbers.

Radioactive substances are the things that put off radiation. These could be radioactive waste, or even radioactive materials not yet used.
There is a lot of radioactivity in nature, and some radioactive things are commonly used, even to the point of being required by law for human safety. Granite is radioactive because of the thorium in it. Many other rocks are radioactive. Cosmic rays bring radioactivity from outer space to all parts of the earth. They reach the ground sometimes, but even when they don't, the radioactive carbon-14 and tritium they produce do, along with other radioactive materials. Nearly 0.016% of all potassium is radioactive. This is not much, but it cannot be separated out. We all need the potassium to survive, even though tiny bits of it are radioactive. In order to ban radioactive materials completely, it would be necessary to ban food. All human beings are radioactive from the potassium, the carbon-14, and other natural isotopes; this includes all local politicians. Synthetic radioactive materials are used for diagnosis and treatment of disease. They are used in smoke detectors. Baning radioactive materials would be unhealthy and even make legally require safety equiment illegal. A wise antinuclear activist takes the position that we probably have all the radioactivity we could ever have use for already and do not need any more.
Origin: It's a product of heat and pressure of lesser elements. It is the end of a radioactive decomposition of higher elements. So, it exists whenever these processes are occurring. Generally, produced in stars. Carbon exists in all living things, and is basis for all living organisms. Even, after living things die, they still posses their carbon. (Hence, why we can apply carbon dating to most things.)
Teflon isn't especially "tough"; it's actually fairly weak mechanically because it doesn't stick to anything very well, not even itself. It is very chemically resistant, but that's because the carbon-fluorine bonds are very strong and has nothing to do with the length of the carbon chain.
Any of a variety of elements might do for this, including thorium and uranium, but even potassium has an important radioactive isotope in it.
There are many forms of pyrite, and it is possible that a radioactive isotope may be incorporated, but this is very uncommon. Even then the radioactivity would not be at harmful levels.
it can kill the earth and even us if there is to much
Xenon gas even though it is not radioactive.
No. All things are radioactive, including living things and even humans. All matter (save a few) emits gamma radiation spontaneously.
Elements that decay (give off protons and neutrons) to form other elements. *It's not elements as such that are stable or unstable, but rather isotopes. Even elements of small atomic number have unstable isotopes that undergo radioactive decay, for example carbon-14. Elements with higher atomic numbers than Lead (82) are naturally radioactive in all isotopes. Bismuth (83) has an extremely long half-life, but the time generally becomes shorter (the decay more rapid) as the size of the nucleus gets progressively larger for heavier radioactive elements.
Yes. A compound is a substance made of atoms that are chemically bonded.
