Uranium-234 has half life of 2.48 * 10^5 years

Thorium-230 has half life of 8.0 * 10^4 years

Radium-226 has half life of 1.62 * 10^3 years

Lead-210 has half life of 20.4 years.

The rate constant for the decay of unstable nuclide X by alpha-particle emission is 1.17 * 10^-6 / day. What is identity of X? Use the following table above to assist in answering the question below. Please show step by step. This is too hard and difficult.

**DrBob222**, Tuesday, March 20, 2012 at 3:33pmI believe you are over thinking this.

t_{1/2}in day = 0.693/k

Solve for k and divide by 365 to convert to years. Compare with the list of those given.
