Question

The half‐life of Uranium‐237 is 5.83 x 10^5 seconds. What is the decay constant?

Answer 1

λ = 1.19 x 10⁻⁶

Step-by-step explanation:

The relationship between the half-life of an element and the decay constant of that element is given by the following formula:

`T_(1/2) = (0.693)/(\lambda) \\\\\lambda = (0.693)/(T_(1/2))`

where,

`T_(1/2)` = half-life = 5.83 x 10⁵ s

λ = decay constant = ?

`\lambda = (0.693)/(5.83\ x\ 10^5\ s)`

λ = 1.19 x 10⁻⁶
