How many neutrons does the isotope N-14 have? 6 7 8 9

7

Explanation:

An isotope is an atom that has a different number of neutrons than the standard for that atom.

1)Nitogen -14 has 7 protons in the nucleus for its an isotope of nitrogen which has an atomic number of 7.

2)Now we need to find the number of neutrons. This is implied in the name of the isotope whereby the protons and neutrons add up to its atomic number. So

(14-7 protons= 7 neutrons.)

So it has 7 neutrons.
