The half-life for the decay of radium is 1620 years so the rate constant for this first-order reaction is 4.28 × 10⁻⁴ yr⁻¹
The half-life of any element is the time in which the quantity of that element reduces to half of the original amount. The symbol of half-life is t1/2 and it is mostly used in nuclear chemistry and physics. It gives information about the stability and radioactive decay process of any element or compound.
Half-life of radium (t1/2) = 1620 years
Rate constant = ?
To calculate the rate constant we use the following formula:
K = 0.693 / t1/2
K = 0.693 / 1620
K = 4.28 × 10⁻⁴ yr⁻¹
