No. The activity rate declines exponentially but mathematically, even though it gets closer and closer to zero, it can never attain that value.
Radio activity never stops. Radioactive material emits radioactive rays for ever. How ever it can be capped but when ever the material is exposed it will start emitting gamma and Beta rays.
Radioactivity was discovered in the late 19th century. Radioisotopes have been discovered ever since then.
Francium is a highly radioactive and unstable element that is never found in its pure form in nature. If it were to be touched, it would likely react explosively with water or air. Due to its extreme rarity and radioactivity, no one has ever touched or felt francium.
Hydrogen. It is also the lightest element and the first element that ever formed.
Pitchblende is a radioactive mineral composed of the mineral uraniumite. It is one of the main mineral ores of uranium.
Not unless it becomes another element.
wind
Waste material can be made, into what ever you want it to be!
Since the first element ever produced synthetically was Technetium, then it will be in the Transition Metal block.
lightning
The only element he has an affinity for is wind, which he has fused with the rasengan.
