How much energy would be released if 0.00046 kg of plutonium were converted to energy through radioactive decay?
vagabundo [1.1K]
Rdaioactive  decay results in the formation of a different element. Plutonium decays by emitting alpha emission to form uranium. Thermal energy is emitted as the alpha particles are absorbed and the kinetic energy  is converted to heat. The amount of energy is computed by the formula;
E = mc²
E = 0.000046 × (3 ×10^8) 
 Energy = 4.14 ×10^13 Joules
