Valence Electrons and Electron Arrangement
Determining electron configurations and identifying valence electrons for chemical reactivity.
Key Questions
- Use Bohr diagrams to identify the valence electrons of elements across periods 1 to 3 and describe the pattern you observe moving across each period.
- Explain how the number of valence electrons shown in a Bohr diagram determines whether an element tends to gain, lose, or share electrons when forming compounds.
- Predict whether two given elements are likely to bond by comparing their valence electron arrangements using Bohr diagrams.
