Answer
$N^{13}$ : Protons = 7 neutrons= 6
$N^{14}$ : Protons = 7 neutrons= 7
$N^{15}$ : Protons = 7 neutrons= 8
$N^{16}$ : Protons = 7 neutrons= 9
$N^{17}$ : Protons = 7 neutrons= 10
Work Step by Step
Number of protons = the atomic number of the atom
Since nitrogen's atomic number is 7 the number of protons in all isotopes of nitrogen will be 7.
Number of neutrons = Mass number- number of protons
So, $N^{13}$ : #of neutrons = 13 - 7 = 6
$N^{14}$ : 14-7 = 7 neutrons
$N^{15}$ : 15 -7 = 8 neutrons
$N^{16}$ : 16-7 = 9 neutrons
$N^{17}$ : 17-7 = 10 neutrons
