Answer:

Nitrogen has seven neutrons for this isotope.

Explanation:

Hello, chemistry lover! today we are going to find out how many neutrons nitrogen have in just 3 steps.

To find out the number of neutrons for nitrogen,we have to have knowledge about atomic number,atomic mass,mass number of nitrogen.

Step-1:

●The atomic number of nitrogen is the number of protons in nitrogen's nucleus.

●The atomic mass of nitrogen is the average number of protons plus neutrons of all the isotopes of nitrogen.

●The Masss number of nitrogen is the number of protons plus neutrons of a specific isotope of nitrogen.

Step-2:

We need to convert atomic mass of nitrogen to mass number of nitrogen by rounding if necessary (In case of fraction) .

From periodic table,

●Atomic number of nitrogen is 7(Seven).

●Atomic mass of nitrogen is 14.01

●To find out mass number,we need to round 14.01 to a whole number.So,by rounding,we are getting mass number of nitrogen.The mass number of nitrogen is 14.

Step-3:

By the difference between mass number and atomic number of nitrogen,we get the number of neutrons in nitrogen.

●Number of neutrons=14-7=7
Therefore,the number of neutrons in nitrogen is 7 here for this isotope.

● Number of electrons in nitrogen is 7.Remember that number of electron equals to proton in a neutral atom.

●Number of protons in nitrogen is 7.
