Key concepts
Why it matters
This objective helps connect Group 7 to exam-style questions, flashcards, and revision notes for The periodic table.
Quick student answer
What are and explain why reactivity decreases down Group 7?
Direct answer
In Chemistry, this page helps you answer questions about and explain why reactivity decreases down Group 7 within The periodic table. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are Group 7 and reactivity.
Key terms
- Group 7: A group in the periodic table that contains the halogens, characterized by their reactivity and trends in properties.
- reactivity: The tendency of an element to undergo chemical reactions, which decreases down Group 7 due to increasing atomic size and electron shielding.
Common trap
Reactivity Misunderstanding: Focus on the concept that as you move down Group 7, the outer electrons are further from the nucleus, making it harder for the atom to attract additional electrons, thus decreasing reactivity.
