m(t)=100e−0.000121t. With this formula, we can calculate the amount m of carbon-14 over the years. Every year, the mass m of carbon-14 is multiplied by e−0.000121≈0.999879. After 100 years, 98.7973 nanograms still remain.

What is the electron for carbon-14?

6 electrons A neutral atom would have the same number of protons and electrons, so a neutral atom of carbon-12 or carbon-14 would have 6 electrons. Although neutrons do not carry an electrical charge, they have a mass comparable to that of protons, so different isotopes have different atomic weight.

How does c14 decay to n14?

Carbon-12 and carbon-13 are both stable, while carbon-14 is unstable and has a half-life of 5,730 ± 40 years. Carbon-14 decays into nitrogen-14 through beta decay. A gram of carbon containing 1 atom of carbon-14 per 1012 atoms will emit ~0.2 beta particles per second.
