Here's a breakdown of each:
Carbon-12 (¹²C)
* Atomic number: 6 (meaning it has 6 protons)
* Mass number: 12 (meaning it has 6 protons + 6 neutrons)
* Abundance: ~98.9% of all carbon on Earth
* Stability: Stable isotope
* Use: The basis for the atomic mass unit (amu)
Carbon-14 (¹⁴C)
* Atomic number: 6 (meaning it has 6 protons)
* Mass number: 14 (meaning it has 6 protons + 8 neutrons)
* Abundance: Trace amounts (about 1 part per trillion)
* Stability: Radioactive isotope with a half-life of 5,730 years
* Use:
* Radiocarbon dating: Scientists use the decay of carbon-14 to determine the age of ancient artifacts and fossils.
* Tracing biological processes: Carbon-14 is used to track the movement of carbon through living organisms.
Key differences:
* Number of neutrons: Carbon-14 has two more neutrons than carbon-12.
* Stability: Carbon-12 is stable, while carbon-14 is radioactive and decays over time.
* Abundance: Carbon-12 is much more abundant than carbon-14.
* Applications: Carbon-12 is the standard for atomic mass, while carbon-14 is used for dating and tracing.
In essence, while both isotopes are carbon, their different neutron counts give them unique properties that make them useful in various scientific fields.
