N-14 and N-15 are both stable.
Nitrogen is a non metal element. Atomic mass number of it is 14.
Nitrogen-15 would have 8 neutrons, while nitrogen-9 (if it existed) would only have 2.
an isotope of nitrogen will be formed with two neutrons less compared to the starting isotope
Neutral atom. An atom of nitrogen will also be an isotope of nitrogen.
Nitrogen (the isotope 14N) has 7 neutrons.
Two more neutrons
Nickel has 28 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a nickel isotope = Mass number -28
nitrogen-15
You would need to know how many protons and neutrons are in the nucleus of a particular isotope of nitrogen. The number of protons, which is its atomic number, will always be the same, no matter which isotope is given, but the number of neutrons differs with different isotopes. For example, one isotope of nitrogen has 7 neutrons. To determine its mass number, find nitrogen on the periodic table, and you will see that its atomic number is 7. So this isotope of nitrogen has 7 protons. Now, add the 7 neutrons to the 7 protons, and you get a mass number of 14 for this isotope of nitrogen, which is called nitrogen-14. (Isotopes are named by their mass numbers.) Another isotope of nitrogen has 8 neutrons. Add the 8 neutrons to the 7 protons (atomic number), and you get a mass number of 15 for this isotope of nitrogen, called nitrogen-15.
Nitrogen is a non metal and wants to gain (anion) three electrons making it N^-3 (Nitride ion).
Seven.
Nitrogen isotope of nitrogen are used as tracers in agricultural studies (efficiency of fertilizers), leaks detection in nuclear reactors, etc.
