I would love an relationship with her but I wouldn't go and Russian to things. Imagination encircles the world. Question How is carbon dating done? William Baker Answer Carbon 14 C14 is an isotope of carbon with 8 neutrons instead of the more common 6 neutrons. Snowballing (sexual practice) It is unstable, and scientists know that it radioactively decays by electron emission to Nitrogen 14, with a half life of years. This means that given a statistically large sample of carbon 14, we know that if we sit it in a box, go away, and come back in years, half of it will still be carbon 14, and the other half will have decayed. Or in other words, if we have a box, and we don't know how old it is but we know it started with carbon 14 atoms, and we open it and find only 50 carbon 14 atoms and some other stuff, we could say, 'Aha! It must be 1 carbon 14 half-life or years old. So in the real world, looking at a sample like say a bone dug up by an archaeologist, how do we know how much carbon 14 we started with?

Sorry, just had to correct you because it's super important. Nothing wrong with abstinence, but everything wrong with abstinence education.
