Answer:
The Nitrogen has 7 neutrons.
Explanation:
The Atomic Number is the number of protons of an atom and is represented by Z, so:
Z = number of protons
Z = 7
The Atomic Mass is the sum of the number of protons and the number of neutrons, and is represented by A, so:
A = number of protons + number of neutrons
A = 14
And from A we have that the number of neutrons is:
Number of neutrons = A - number of protons
Number of neutrons = A - Z
Number of neutrons = 14 - 7
Number of neutrons = 7
