How many times fewer neutrons are contained in the nucleus of a nitrogen atom with mass and charge numbers 14 and 7 than a zinc nucleus with mass and charge numbers 65 and 30?
The number of neutrons is defined as the difference between the mass number and the charge number (the number of protons).
the number of neutrons in a nitrogen atom:
n (N) = 14 – 7 = 7;
The number of neutrons in a zinc atom:
n (Zn) = 65-30 = 35;
n (Zn) – n (N) = 35 – 7 = 28.
Answer: there are 28 more neutrons in the zinc atom than in the nitrogen atom.
