Solution

Solution Steps

Step 1: Identify the Given Information

We are given the atomic number and the mass number of xenon:

Atomic number (\(Z\)) = 54
Mass number (\(A\)) = 108

Step 2: Understand the Relationship Between Atomic Number, Mass Number, and Neutrons

The atomic number (\(Z\)) represents the number of protons in the nucleus of an atom. The mass number (\(A\)) is the total number of protons and neutrons in the nucleus.

Step 3: Calculate the Number of Neutrons

The number of neutrons (\(N\)) can be calculated using the formula: \[ N = A - Z \]

Substituting the given values: \[ N = 108 - 54 \] \[ N = 54 \]
