Is nitrogen-16 stable or radioactive?
Nitrogen
| Mass Number | Half-life | Decay Mode |

| 14 | STABLE | – |
| 15 | STABLE | – |
| 16 | 7.13 seconds | Beta-minus Decay |
| Beta-minus Decay with delayed Alpha Decay |
Is nitrogen-15 stable or unstable?
Nitrogen-15 is a rare stable isotope of nitrogen. Two sources of nitrogen-15 are the positron emission of oxygen-15 and the beta decay of carbon-15.
Is O 16 A stable isotope?
Naturally occurring oxygen is composed of three stable isotopes, 16O, 17O, and 18O, with 16O being the most abundant (99.762% natural abundance). Both 17O and 18O are secondary isotopes, meaning that their nucleosynthesis requires seed nuclei.
Is N 15 radioactive?
Some isotopes of nitrogen are unstable. They give out radiation to become more stable; we say they are radioactive. Nitrogen-14 and nitrogen-15 are both stable isotopes of nitrogen.
Is N 14 or N 15 more abundant?
therefore we can conclude that the nitrogen-14 is more common than nitrogen-15.
Is carbon 11 stable or unstable?
Given enough neutrons, a nucleus with many protons can become stable. Notably, the neutrons do not change the chemical behavior of the atom. A carbon atom will not hold together unless it has at least 6 neutrons (i.e., Carbon-11 does not exist because the repulsive force is too strong).
Why is oxygen 16 more stable?
Oxygen Isotopes While most oxgen atoms have a mass of 16 (8 protons and 8 neutrons), a small number of oxygen atoms have a mass of 18 (8 protons and 10 neutrons). Both of these isotopes are stable; they do not undergo radioactive decay.
Why is oxygen 16 an isotope?
Isotopes are elements that contain the same amount of protons, but differ in the number of neutrons in their nuclei. Therefore, oxygen 16 has 8 protons and 8 neutrons, oxygen 17 has 8 protons and 9 neutrons, and oxygen 18 has 8 protons and 10 neutrons.
How many neutrons does oxygen 16 have?
8 neutrons
Oxygen Isotopes While most oxgen atoms have a mass of 16 (8 protons and 8 neutrons), a small number of oxygen atoms have a mass of 18 (8 protons and 10 neutrons). Both of these isotopes are stable; they do not undergo radioactive decay.
Which is the rare stable isotope of nitrogen?
Nitrogen-15 is a rare stable isotope of nitrogen. Two sources of nitrogen-15 are the positron emission of oxygen-15 and the beta decay of carbon-15.
Where does nitrogen 14 and nitrogen 15 come from?
Like all elements heavier than lithium, the original source of nitrogen-14 and nitrogen-15 in the Universe is believed to be stellar nucleosynthesis, where they are produced as part of the carbon-nitrogen-oxygen cycle . Nitrogen-14 is the source of naturally-occurring, radioactive, carbon-14.
What is the half life of nitrogen 14?
Nitrogen-14. Nitrogen-14 is the source of naturally-occurring, radioactive, carbon-14. Some kinds of cosmic radiation cause a nuclear reaction with nitrogen-14 in the upper atmosphere of the Earth, creating carbon-14, which decays back to nitrogen-14 with a half-life of 5,730±40 years.
