Open in App
Solution
The correct option is A 7 days
If 2 g of an isotope has a half-life period of 7 days, the half -life period of 1 g sample is 7 days. Radioactive decay is first order process for which half life period is independent of initial concentration (or mass or number of moles) of isotope.
