Nucleon Conservation Analysis

Analyze the current core reaction. During nuclear fusion, atoms change, but the total number of protons (P) and neutrons (N) is conserved.

Waiting for fusion to begin...
CCC: Energy and Matter. In nuclear processes, atoms are not conserved, but the total number of protons plus neutrons is conserved.
