I assume you meant phosphorous.
Do you mean which chemical element, carbon or phosphorous, is most stable at STP? I suggest you learn some General Chemistry before posting here, this is not the forum to teach you chemistry (or English). A good place for you to start is to read Wikipedia on Carbon and Phosphorous (etc.). Both N and S are found elementally, but S is not stable elementally at STP over the long term. The answer to your third question is: their nature. More precisely, the relative free energy of the products compared to that of the reactants. I am sorry if this answer means nothing to you, you need to be able to walk before you can run.
