WebThe rate for radioactive decay is: decay rate = λN with λ = the decay constant for the particular radioisotope. The decay constant, λ, which is the same as a rate constant discussed in the kinetics chapter. It is possible to express the decay constant in terms of the half-life, t1/2: λ = ln 2 t 1 / 2 = 0.693 t 1 / 2 or t 1 / 2 = ln 2 λ = 0 ... WebJul 29, 2014 · Write a balanced nuclear equation for the α decay of polonium-208. Solution The unbalanced equation is 208 84 Po → 4 2He +X The superscript of X must be 208 – 4 = 204. The subscript of X must be 84 – 2 = 82. Element 82 is Pb. So the equation is 208 84 Po → 4 2He +204 82 Pb Here is a video that describes how to write equations for alpha decay.
