What element has a half-life of only 8 seconds?
The answer is Radium
If Astatine-218 has a half-life of 1.6 s Suppose you have a 1.2-g sample of astatine-218 How much of the sample remains unchanged after 6.4 seconds Explain how you solved the problem?
After 1.6 seconds, 0.6 g astatine-218 remains unchanged. This amount is reduced by half to 0.3 g at 3.2 seconds. It is halved again at 4.8 seconds to 0.15 g, and halved once more to 0.075 g unchanged after a total of 6.4 seconds.

How many grams of radium-222 remain in a 12-gram sample after 76 seconds?
After 76 seconds, half of the radium-222 would have decayed (its half-life is about 3.8 days). Therefore, the quantity of radium-222 remaining in the 12-gram sample would be 6 grams.
Isotope A has half-life of seconds and isotope B has a half-life of millions of years which isotope is more radioactive?
Isotope A is more radioactive because it has a shorter half-life, indicating a faster rate of decay. A shorter half-life means that more of the isotope will undergo radioactive decay in a given time period compared to an isotope with a longer half-life.
