What is radioactive nitrogen?
Unstable isotopes of nitrogen that decay or disintegrate emitting radiation. N atoms with atomic weights 12, 13, 16, 17, and 18 are radioactive nitrogen isotopes.
Is nitrogen 18 stable or radioactive?
Nitrogen-14 and nitrogen-15 are both stable isotopes of nitrogen. However, the other 5 isotopes are all unstable. Nitrogen-12 and nitrogen-13 will decay by beta plus emission and nitrogen-16, nitrogen-17 and nitrogen-18 decay by beta minus emission. Every element has a number of different isotopes.
What is the mass number of nitrogen?
14.0067 u
Nitrogen/Atomic mass
What is the mass number of nitrogen 17?
17.01388
The protons were counted at 90°, in the laboratory system, from the forward direction of the lithium beam. The group of highest energy gave an (M−A) value of 12.92±0.06 Mev for the N17 ground state, corresponding to a physical atomic weight of 17.01388±0.00006.
What is the mass of nitrogen-15?
15.000109

Why is nitrogen-14 an isotope?
Isotopes are atoms that have the same number of protons but different numbers of neutrons in the nucleus. You know that nitrogen-14 has 7 protons in the nucleus because it is an isotope of nitrogen, which has an atomic number equal to 7 . The mass number of an isotope is added to the name of the isotope.
What is the atomic mass of nitrogen-15?
How is nitrogen-14 used?
N-14 is used for the production of the PET radioisotope C-11. It can also be used for the production of the PET radioisotopes N-13 and O-15. Trace Sciences is your most reliable supplier of stable Nitrogen Isotopes.
