Explanations: answer key for all 10 questions

Q1: What particles make up an atomic nucleus?
Answer: Protons and neutrons
They are held together by the strong nuclear force.
Q2: Who discovered radioactivity in 1896?
Answer: Henri Becquerel
He found uranium salts fogged photographic plates.
Q3: Which type of radiation can be stopped by a sheet of paper?
Answer: Alpha
Gamma rays need thick lead or concrete.
Q4: What is a half-life?
Answer: Time for half of a radioactive sample to decay
Half-lives range from fractions of a second to billions of years.
Q5: What is nuclear fission?
Answer: Splitting a heavy nucleus
It releases large amounts of energy.
Q6: What powers the Sun?
Answer: Nuclear fusion of hydrogen into helium
Fusion releases more energy per mass than fission.
Q7: Who led the first controlled nuclear chain reaction in 1942?
Answer: Enrico Fermi
It happened under a stadium in Chicago.
Q8: Which element is the most common fuel in nuclear power plants?
Answer: Uranium
Uranium-235 splits easily.
Q9: Which international fusion project is being built in France?
Answer: ITER
It aims to show fusion can produce net energy.
Q10: Which radioactive isotope dates ancient organic remains?
Answer: Carbon-14
It decays with a half-life of about 5,730 years.

Nuclear Physics Quiz – Energy From the Atom

Nuclear physics studies the nucleus at the center of every atom. Some nuclei are unstable and release radiation as they decay, a process discovered by Henri Becquerel and studied by Marie and Pierre Curie.

Nuclear reactions release enormous energy. Fission splits heavy nuclei like uranium and powers nuclear plants, while fusion joins light nuclei and powers the Sun and stars. Scientists are working to build fusion reactors as a clean energy source.

Nuclear physics has many uses beyond power: cancer treatments, medical imaging, smoke detectors and radiocarbon dating. It also brought nuclear weapons, making safety and international cooperation essential.
