Any substance which is emitting ionizing particles is radioactive. An example is the metal called Plutonium.
The "radioactive" safety symbol warns you that radioactive material or a radiation producing machine is near the symbol and you should take precautions to ensure that you are not unnecessarily exposed to ionizing radiation.

No, graphite is not radioactive.
No, water is not radioactive.
Yes, it is possible for water to become radioactive if it comes into contact with radioactive materials or is contaminated by radioactive substances.
Your question is unintelligible. There is no "radioactive zone" defined as part of the Sun.
Actinium is a radioactive element with symbol Ac.
The meaning of radioactive is: an unstable element which emit radiations as alpha, beta, gamma etc.
No radioactive isotopes of neon are ordinarily found in nature. All elements have radioactive synthetic isotopes, however.

A radioactive noble gas is a noble gas element that has unstable isotopes, meaning they undergo radioactive decay. An example is radon, which is naturally occurring and emits alpha particles as it decays. These gases can pose health risks if inhaled, as their radioactive decay products can damage cells in the respiratory system.
The correct root word for the word "radiation" is "Radiate".
Radioactive decay follows first-order kinetics, meaning the rate of decay is proportional to the amount of radioactive material present. This means that half-life remains constant throughout the decay process.
Mercury is a stable element, meaning it does not naturally undergo radioactive decay. However, certain isotopes of mercury can be radioactive if they are artificially produced in a lab. Overall, mercury is known for its liquid form at room temperature, high toxicity, and ability to form amalgams with other metals.
A stable isotope is an isotope that does not undergo radioactive decay, meaning its nucleus is stable and does not change over time. These isotopes have a constant number of protons and neutrons, making them suitable for use in scientific studies like tracing biological processes or determining the age of rocks. Examples include carbon-12, oxygen-16, and nitrogen-14.
Yes, radon is a radioactive gas that is naturally occurring in the environment. It is colorless, odorless, and tasteless, making it difficult to detect without special equipment. Radon is a known carcinogen and exposure to high levels of radon gas can increase the risk of lung cancer.
