Calcium 42
Nuclear structure of

Calcium 40 

(stable). Move mouse on image for Calcium 42i nuclear structure (a Ca42 isomer nucleus)

Blue toruses = 40 protons
Red toruses = 20 nuclear electrons

Atomic number of Ca (20) = protons (40) - nuclear electrons (20)

The central rod of Ca40 analogous with Oxygen 16 (stable) nucleus. Ca40 = O16 + 6 alpha particles
