Verified step by step guidance1
Identify the atomic number of carbon, which is the number of protons in the nucleus. For carbon, this is 6 protons.
Understand that the mass number of an isotope is the sum of protons and neutrons in the nucleus. For carbon-14, the mass number is 14.
Use the formula: \( \text{Number of Neutrons} = \text{Mass Number} - \text{Number of Protons} \).
Substitute the known values into the formula: \( \text{Number of Neutrons} = 14 - 6 \).
Calculate the number of neutrons by performing the subtraction to find the result.
