🔍 Key Concepts

• Ozone layer function in the stratosphere • How halogen elements (group 17 on the periodic table) behave in the upper atmosphere • Difference between elemental form vs part of a compound (like CFCs – chlorofluorocarbons)

💭 Think About

• Which of these elements is commonly discussed in connection with CFCs and ozone depletion in environmental regulations and textbooks? • Think about which element can form very stable compounds that survive long enough to reach the stratosphere before breaking down. • Of the four options, which one is specifically mentioned in discussions of the Antarctic ozone hole and the Montreal Protocol?

✅ Before You Answer

• Remember that the problem is about eventually reaching the stratosphere, not just reacting in the lower atmosphere. • Focus on which element forms stable man‑made compounds that are known to damage ozone once they break apart high in the atmosphere. • Eliminate choices that are mostly discussed as major greenhouse gases or inert background gases, not as the main cause of ozone layer destruction.
