The half-life of Zn-71 is 2.4 minutes. If one had 100.0 g at the beginning, how many grams would be left after 7.2 minutes has elapsed?
7.2 / 2.4 = 3 half-lives
12.5 g remaining

Both Fission and Fusion reactions release massive amounts of energy in the form of heat and gamma radiation. However, one of these two is more energetic than the other. Which process, fission or fusion releases more energy?
Fusion! It's what powers the sun and why hydrogen bombs are MUCH more scary than uranium bombs.

Put the three most common types of Nuclear Decay in order from least penetrating to most penetrating.
Alpha Decay
Beta Decay
Gamma Decay
500

What is the last stable element on the periodic table of elements?
Lead (82 atomic number)/Bismuth (83 atomic number)
Any element above 82/83 tends to be unstable and thus radioactive.
