The decay of a radioactive element is a random process which is governed by the laws of chance. The rate of decay only depends on the number of undecayed atoms. This means that the …

How would you write a balanced nuclear equations for the emission of an alpha particle by polonium-209 and for the decay of calcium-45 to scandium-45? When a 226/88Ra nucleus …

May 7, 2018 · We begin with 20g of a certain radioactive isotope. As it decays, the amount remaining at time t (hrs) is A = 20e-0.08t. What is its rate of decay at time t = 8 ? solution …

Radioactive decay is a process in which an unstable nucleus emits alpha particles (α), beta particles (β), or gamma rays (γ) and becomes a different nucleus.
