1.	Which of the following has the highest value of radioactivityA. 1 g of RaB. 1 g of `RaSO_(4)`C. 1 g of `RaBr_(2)`D. 1 g of Ra `(HPO_(4))`
Answer» Correct Answer - A Radioactivity follows `1^(st)` order kinetics. So greater the concentration of radioactive nuclide, greater will be the radioactivity. Since 1 g of Ra has maximum number of radioactive nuclides as compared to 1 g `RaSO_(4) or RaBr_(2) or Ra(HPO_(4))`. So it will have the highest value of radioactivity
