You are talking about a natural isotope of nitrogen i.e Nitrogen-15 which has atomic number same as nitrogen (7) ans mass number 1 greater than standard nitrogen (i.e 15 as Nitrogen's mass no. is 14).
Nitrogen-15 has i neutron more than standard nitrogen

What is a isitope?
Do you mean ISOTOPE? an isotope is a from of an element which has the same number of protons and electrons but a different number of neutrons. examples: chlorine (Cl) has an atomic massof 35.5 because of its isotopes. the same is apparent of bromine.
When masses of all naturally occurring isotopes of a particular element are averaged the result is called the elements?
When the mathematical products of the mass of each naturally occurring isotope of a particular element, each mass being multiplied by the natural abundance fraction* of the particular isotope, are added, the result is called the element's atomic weight or, if the masses are expressed in grams per Avogadro's Number of atoms, the gram atomic mass._____________________________*The abundance fraction equals exactly 0.01 times the percent abundance of the isotope.
Which isotope contains the greatest number of protons?
Atomic number is a measure of protons and electrons. extra or less Neutrons are what make an isotope and are not included in atomic number. therefore element with the highest atomic number will also be the isotope with the highest atomic number. on my periodic table it is lawrencium at 103. (note although this might have extra neutrons making it an isotope, it will always have the same atomic number - atomic number isn't what determines an isotope it is mass number) if you meant mass number (which is what determines an isotope), you can subtract the atomic number from the mass number to find out how many neutrons there are and determine whether it is an isotope or not
How many neutrons is in californium?
153 neutrons in the most stable isotope Number of neutrons = Atomic mass of an isotope - atomic number. Atomic mass of the most stable isotope of Cf is 251. Atomic number of Cf is 98.
How much neutrons are in xenon?
Each isotope of an element has a different number of neutrons. Number of neutrons = Atomic mass of the isotope - Atomic number of the element The atomic number of xenon is 54. For the list of xenon isotopes see the link below.
What are the atomic number and atomic mass number of?
The atomic number of an element is the number of protons in the nuclei of its atoms. Mass number is the sum of protons and neutrons in the atomic nucleus of a particular isotope of an element.
What is the average atomic mass of an element is the average atomic masses of what kind of isotopes?
average atomic massof an element=(Atomic mass of first isotope X % of that isotope) + (Atomic mass of second isotope X % of the second isotope)
How is the mass number of an isotope different from the average atomic mass that is on the periodic table?
The mass number for a particular isotope of an element is a precise value. The average atomic mass for an element is the value you would measure for that element given all the isotopes it has and their abundance in the sample.
An isotope shares the atomic number with its element atom How does it differ from the element atom?
An isotope shares the atomic number with its element atom. How does it differ from the element atom?
What is the atomic number of isotope?
Well all Isotopes have the same atomic number so if you have the element the atomic number of an element with that same isotope is that same atomic number.
How do you decide a element is a isotope or ion?
An isotope has a different number of neutrons and therefore a different atomic mass. An ion has a different number of electrons from protons and therefore carries an electric charge
Why need to know the percentage of each isotope of an element to determine the atomic mass?
Because each isotope of an element has a mass different from any other isotope of the same element, and the atomic mass of an element is an average, weighted by the proportion of each isotope, in the naturally occurring element.
What element has the atomic mass of 22?
An isotope of Neon. This isotope accounts for between a fifth and a quarter of the element.
Which isotope has 17 neutrons and an atomic mass of 32?
The number of protons is the atomic mass minus the number of neutrons; in this instance 32 - 17 or 15. An atomic number of 15 corresponds to the element phosphorus; therefore, the isotope is P-32.
When the masses of all naturally occurring isotopes of a particular element are averaged the result of the elements?
When the mathematical products of the mass of each naturally occurring isotope of a particular element, each mass being multiplied by the natural abundance fraction* of the particular isotope, are added, the result is called the element's atomic weight or, if the masses are expressed in grams per Avogadro's Number of atoms, the gram atomic mass._____________________________*The abundance fraction equals exactly 0.01 times the percent abundance of the isotope.
Isotope of an element?
The isotope of an element is the different versions of that element. Due to the different number of neutrons. So the same element can have different numbers of neutrons in it's nucleus and therefore different mass numbers e.g. Chlorine 35 or Chlorine 37. Both contain identical numbers of protons but different numbers of neutrons.
What is the relationship between two element X and Y whose atomic numbers are 18 and 20 but their mass number remains same as 40?
There is no relationship other than having the same mass number. Element X has an atomic number of 18, which makes it the noble gas argon. The particular isotope is argon-40, which means that the atomic nuclei of this isotope of argon contain 18 protons and 22 neutrons. Element Y has an atomic number of 20, which makes it the alkaline earth metal calcium. The particular isotope is calcium-40, which means the atomic nuclei of this isotope of calcium contain 20 protons and 20 neutrons.
