The rate at which a certain element decay is proportional to the number of such element that are present in the given sample. Half of the original number of elements have undergone disintegration in a period of 1000 years. (a) what percentage of the number of radioactive element will remain after 3000 years?(b) In how many years will only 10% of the original number remain?
