Do the carbon-14 atoms decay turn into nitrogen-14 at the same time?
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….Carbon-14.

What is the relationship between carbon-14 and nitrogen-14?
The relationship between carbon-14 and nitrogen is that carbon-14 forms from nitrogen atoms and eventual decays into atoms of nitrogen-14.
What kind of decay must carbon-14 undergo to generate nitrogen-14?
beta decay
Carbon-14 undergoes beta decay to the stable nitrogen-14 isotope.
What happens to carbon-14 when it undergoes radioactive decay?
The type of radioactive decay that carbon-14 undergoes (called beta decay) changes it from radioactive carbon to a plain-old stable atom with seven protons and neutrons — nitrogen. It’s happening in us right now, because a tiny fraction of the carbon in the food we eat is radioactive carbon-14.
How does carbon-14 decay into nitrogen?
C decays by a process called beta decay. During this process, an atom of 14C decays into an atom of 14N, during which one of the neutrons in the carbon atom becomes a proton. This increases the number of protons in the atom by one, creating a nitrogen atom rather than a carbon atom.
How long does it take carbon-14 to become nitrogen-14?
5730 years
Whereas its cousins take mere minutes or hours to decay, only half of the carbon-14 component of a given substance is gone after 5730 years, having become nitrogen-14.
Why does carbon-14 decay into nitrogen?
Carbon-14 is a rare version of carbon with eight neutrons. It is radioactive and decays over time. When carbon-14 decays, a neutron turns into a proton and it loses an electron to become nitrogen-14.
What happens in beta decay?
Beta decay occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other. In beta minus decay, a neutron decays into a proton, an electron, and an antineutrino: n Æ p + e – +.
How is nitrogen converted to carbon-14?
Neutrons are ejected from nuclei of the upper atmosphere in collisions with cosmic rays (A). Captured by nitrogen nuclei (N-14), neutrons transform these nuclei into carbon-14 (B). The carbon-14 atoms combine with the oxygen in the air to form carbon dioxide (C).
How does carbon 14 decay into nitrogen 14?
Carbon 14 decays by beta emission into Nitrogen 14. Carbon 14 has 6 protons and 8 neutrons and is radioactive. It has a half life of about 5,730 years. This means that after 5,730 years half of the atoms will have decayed.
Why is the beta decay of carbon 14 unstable?
Carbon 14 is unstable because it has too many neutrons. It decays by beta emission where one of the neutrons gets converted into into a proton an electron and an electron anti-neutrino.
How many protons and neutrons are in Carbon 14?
The carbon 14 nucleus undergoes beta minus decay, in which a neutron changes into a proton and emits an electron and an antineutrino. The net result is that the carbon 14 nucleus with 6 protons and 8 neutrons is changed into a Nitrogen 14 nucleus with 7 protons and 7 neutrons.
What happens to C14 when it decays?
The C14 decays into Nitrogen 14 whereby a so called “extra neutron” changes into a proton and an electron that takes its place in the outer ‘orbital’. The 2 extra “neutrons” have changed into a “neutron-proton” pair as is depicted below. This in turn means the element # has increased by one, becoming Nitrogen.
