Example 3

easy
Calculate the number of neutrons in 2656Fe{}^{56}_{26}\text{Fe}.

Solution

  1. 1
    Mass number A=56A = 56, atomic number Z=26Z = 26.
  2. 2
    Neutrons =A−Z=56−26=30= A - Z = 56 - 26 = 30.

Answer

30 neutrons30\text{ neutrons}
Always subtract the atomic number from the mass number to find the neutron count.
