Identify the atomic number (Z) of silver, which is the number of protons. For silver, Z = 47.
Understand that the mass number (A) is the total number of protons and neutrons in the nucleus. Here, A = 108.
Recall the relationship: \(A = Z + N\), where \(N\) is the number of neutrons.
Rearrange the formula to solve for neutrons: \(N = A - Z\).
Substitute the known values: \(N = 108 - 47\), which gives the number of neutrons in the silver atom.
