The conservation of mass requires that the other product have A = (2 × 12) − 20 = 4; because of conservation of charge, it must have Z = (2 × 6) − 10 = 2. These are the characteristics of an α particle. The reaction is therefore. (1.2.2) 6 12 C + 6 12 C → 10 20 N e + 2 4 α. Summary The Dahlgren-Whitehead rainbow is a model for determining health inequalities that maps the relationship between the individual, their environment and health.
