Carbon-12 and carbon-13 are stable.
The fact that carbon-14 is unstable, with a relatively short half-life (very short compared to the age of the Solar System) means that it must needs have been produced more recently than the creation of the Solar System.
Scientists know that the isotopes Carbon-12 and Carbon-14 are both forms of carbon, but they differ in the number of neutrons they contain. Carbon-12 is the most common form of carbon and is stable, while Carbon-14 is radioactive and is used in radiocarbon dating to determine the age of organic materials.
C-13 has an atomic number of 6 and an atomic mass of 13, therefore it has 13-6 neutrons = 7. C-14 therefore has 8 neutrons. N-14 has an atomic mass of 14 and an atomic number of 7, so its number of neutrons is 7. 8>7, so Carbon 14 has the largest number of neutrons.
Yes. Well it depends on how much you start with. Numerically the exponential decay curve approaches zero without touching it, but in reality, matter is composed of elemental particles. Consider that at the end of 10 half lives, you had a single atom of Carbon14. So at 9 half lives, there should be 2 Carbon14 atoms. If you keep going, then at the start, you had 1024 atoms. And that is a teeny tiny amount. To put in perspective, if you have one mole of Carbon 14 (that is 14 grams) But there are 6.023 x 10^23 atoms. It would take 79 half-lives to get down to just a single atom of Carbon 14. In reality, it is a little more complex than this, but this should put it in perspective.
Carbon-14 dating is not accurate for materials older than 50,000 years because the half-life of carbon-14 is about 5,730 years, meaning it decays rapidly over time, making it ineffective for measuring ancient material. Beyond this age, the amount of carbon-14 left in a sample is so small that it becomes difficult to accurately measure, leading to less reliable age estimates. Other dating methods, such as potassium-argon or uranium-lead dating, are better suited for older materials.
I'm almost positive the protons always tell you the identification of an element on the periodic chart... the atom with 6 protons is Carbon a non metal but if electrons are 5 then it must be carbon cation C+.
On many Periodic Tables, the small number directly below the chemical symbol is the atomic mass. On mine, there is a small 12.011 under the large C for carbon. While most carbon is 12, there are naturally occurring carbon13 and carbon14, so this is an average mass of all naturally occurring isotopes, with the majority of isotopes being carbon12

Carbon-12 is the most common form of carbon and is stable, while Carbon-14 is radioactive and is used in radiocarbon dating to determine the age of organic materials.
Carbon-14 contains more neutrons compared to carbon-12. Carbon-12 has 6 neutrons, while carbon-14 has 8 neutrons. The number of protons and electrons in both carbon isotopes remains the same, at 6 each.
The main limitations of using Carbon14 dating to find the age of something that is carbon base are firstly the possibility that carbon may be absorbed by some things making it more difficult to get an absolutely accurate age and secondly, with Carbon14 only having a half life of 5,568 years the maximum theoretical limit for detection is 100,000 years.
Carbon is a non metallic element. Mass number of it is 12.
Carbon14 dating (isotopic dating)
7 protons, 7 neutrons and 7 electrons
elements exist in more than one form eg carbon 12 and carbon14
C-13 has an atomic number of 6 and an atomic mass of 13, therefore it has 13-6 neutrons = 7. C-14 therefore has 8 neutrons. N-14 has an atomic mass of 14 and an atomic number of 7, so its number of neutrons is 7. 8>7, so Carbon 14 has the largest number of neutrons.
scientists use carbon14 and potassium argon to find absolute age of rock

The half life of C14 is about 5700 years, so items that are a few multiples of this time are suitable for carbon14 dating. Most archaeological items are suitable, and some young fossils.
