Question 1: Noble gases are a group of elements known for their lack of reactivity due to their full outer electron shells. Name the six noble gases found in Group 0 of the periodic table.

Answer: Helium, Neon, Argon, Krypton, Xenon, Radon

Question 2: Explain why noble gases are generally unreactive.

Answer: Because they have a full outer electron shell, making them stable and unlikely to react with other elements.

Question 1: Calculate the atomic number of Xenon if the number of neutrons is 108 and the atomic mass is approximately 131.

Answer: 23

Question 2: Identify a common use of Helium in industry.

Answer: Inflating balloons and airships

Question 3: Multiple Choice: Which noble gas is most commonly used in fluorescent lighting?

Answer: Neon

Question 1: Describe a simple experiment to demonstrate the inertness of noble gases. Include the variables involved and safety precautions.

Answer: A common experiment involves placing a noble gas sample in a sealed container and attempting to react it with a reactive substance such as oxygen or hydrogen. The variables include the type of noble gas, the reactive substance, temperature, and pressure. Safety precautions include working in a well-ventilated area, wearing safety goggles and gloves, and handling gases with proper equipment to prevent leaks or accidents.

Question 1: A sample of Argon is used in an experiment and produces a glow when an electric current is passed through it. What property of Argon explains this phenomenon?

Answer: Its ability to emit light when excited by an electric current due to its atomic structure.

Question 1: Explain how Xenon is used in medical imaging technology.

Answer: Xenon gas is inhaled in a controlled manner to produce images of the brain and lungs using a process called Xenon-133 scanning, which takes advantage of its radioactivity and inertness.
