Quick explanation
Link block classification to electron configuration
- This point belongs to Periodicity, especially Classification.
- You need to be able to link block classification to electron configuration.
- The key ideas to know are electron configuration.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect Classification to exam-style questions, flashcards, and revision notes for Periodicity.
Quick student answer
Which of the following elements has the highest first ionization energy?
Direct answer
Argon (Ar) has the highest first ionization energy due to its full outer electron shell, which makes it more stable and requires more energy to remove an electron.
Key terms
- Electron Configuration: The distribution of electrons in an atom's electron shells and subshells, which determines its chemical properties.
- Periodic Trends: Patterns observed in the periodic table, such as ionization energy, electronegativity, and atomic radius, that vary predictably across periods and groups.
Common trap
Confusing groups and periods: Remember that groups are vertical columns indicating elements with similar properties, while periods are horizontal rows indicating elements with increasing atomic number.
