A certain radioactive element has a half liv of 20days, how long does it take 3/2 of the atom originally present to disintegrate
To determine how long it takes for 3/2 of the atoms originally present to disintegrate, we need to find the decay constant (λ) of the radioactive element. The decay constant (λ) can be calculated using the half-life (T½) formula:
λ = ln(2) / T½
Given that the half-life of the radioactive element is 20 days, we can substitute this value into the formula:
λ = ln(2) / 20
Now we can calculate the decay constant (λ).
