Answer:

Is the mass number

Explanation:

Every atom is usually identified by using two different numbers:

- Atomic number: generally labelled with Z, corresponds to the number of protons in the nucleus, so Z = p

- Mass number: generally labelled with A, corresponds to the number of protons+neutrons in the nucleus, so A = p + n

To find the number of neutrons in a nucleus, therefore, we can do

n = A - Z
