Given information
Half life, billion years
Percent of atoms decay
Name of element =
Initially contained atoms.
Time it would take to decay of atoms = ?
Step-by-step explanation
Step 1.
Let the total percent of atoms be .
Percent of atoms decay
Percent of atoms remain
Therefore,
where, remaining atoms
initial atoms
The half-life is independent of initial concentration shows the reaction is first order. For the first-order reaction, the half-life for first-order reaction is given by the formula,
Substitute the value in the above equation,
