| What title did Napoleon give himself in 1804? | Emperor of the French. |
| What was the Napoleonic Code? | A uniform system of laws established by Napoleon that emphasized equality before the law, religious tolerance, and merit-based advancement. |
| What were some of Napoleon’s reforms in France? | Improved education, stabilized the economy, established the Bank of France, and centralized government administration. |
| What was the Continental System? | Napoleon’s policy of blocking British trade with Europe to weaken Britain’s economy. |
| What campaign led to Napoleon’s downfall? | Russian battle |
| What is radioactivity (or radioactive decay) | The spontaneous emission of particles or energy from an unstable nucleus. |
| What is transmutation? | When an atom’s nucleus changes into a different element during radioactive decay. |
| What is a radioisotope? | An isotope with an unstable nucleus that undergoes radioactive decay. |
| What are the three main types of radiation? | Alpha particles, beta particles, and gamma radiation. |
| What makes a nucleus unstable? | An uneven ratio of neutrons to protons, especially when atomic number > 83. |
| What is half-life? | The time required for half of a radioactive sample to decay. |
| Does half-life depend on temperature or pressure? | No, it stays constant regardless of conditions. |
| What happens to a 20 g sample after 3 half-lives? | A: 2.5 g remains (20 → 10 → 5 → 2.5). |
| What is the half-life of Carbon-14? | About 5730 years. |
| What is artificial transmutation? | A man-made nuclear reaction caused by bombarding a nucleus with particles. |
| What is nuclear fusion? | Two small nuclei combine to form one larger nucleus, releasing energy. |
| What powers the sun | Nuclear fusion of hydrogen isotopes into helium. |
| What is nuclear fission? | large nucleus splits into smaller ones, releasing energy and neutrons. |
| What is a chain reaction? | Neutrons from fission cause more nuclei to split, repeating the process. |
| How is Carbon-14 used? | For dating once-living materials. |
| How is Uranium-238 used? | To date rocks and determine geological age. |
| What are medical uses of radioisotopes? | I-131 treats thyroid disorders; Co-60 kills cancer cells; Tc-99 detects cancer. |
| What are industrial uses of radioisotopes? | To measure thickness or detect flaws in materials. |
| What are some dangers of radiation? | It can damage healthy tissue, cause illness, genetic mutations, and nuclear waste issues. |
