The atomic number of a neutral atom is equal to the number of protons and the number of electrons of the atom. The atomic weight meanwhile is equal to the sum of the number of protons and number of neutrons. nitrogen has 7 protons or electrons. hence nitrogen -14 has 7 neutrons while nitrogen -15 has 8 neutrons. answer is D
