Explain the alpha-particles ionize molecules in the air

Reference no: EM13242048

One type of commercial smoke detector contains a minute amount of radioactive americium-241 (241Am), which decays by alpha-particle production. The alpha-particles ionize molecules in the air, allowing it to conduct an electric current. When smoke particles enter, the conductivity of the air changes and the alarm buzzes. (a) Write the equation for the decay of (mass number 241, protons 95) by alpha-particle decay.
