The half-life of radium is 1690 years. If 60 grams are present now, how much will be present in 460 years?
Solutions
Expert Solution
Radium is a radioactive element. The phenomenon of spontaneous
disintegration of element is known as radioactivity. We can find
amount of radioactive element after some time like as 460 years
with the help of law of radioactivity decay .

Radium-226 is a decay product of 238U . 226Ra has a half-life of 1600 years and is found in uranium ores
Radium-226 is a decay product of 238U . 226Ra has a half-life of 1600 years and is found in uranium ores. When it was first discovered and before radioactive decay was well understood, some mineral prospectors claimed to have discovered a rich deposit of radium (a few percent by mass) in a cave in the American midwest. What do you think of this claim?
