The isotope notation for carbon-14 is written as 614C. This notation includes the chemical symbol for carbon, which is C, along with two numbers: the atomic number and the mass number.
The atomic number, which is 6 for carbon, is represented as a subscript (the smaller number at the bottom). This indicates the number of protons in the nucleus of the carbon atom. The mass number, which is 14 for carbon-14, is represented as a superscript (the larger number at the top). This number represents the total number of protons and neutrons in the nucleus.
In the case of carbon-14, it has 6 protons and 8 neutrons (14 – 6 = 8). Carbon-14 is a radioactive isotope of carbon commonly used in radiocarbon dating, which helps determine the age of organic materials.
