What is valence?
Think about the electrons involved in bonding.
Define oxidation state.
Relate this to how electrons are gained or lost.
What oxidation state does oxygen typically exhibit in Na₂O?
Consider how many electrons oxygen receives from sodium.
True or False: Electronegativity affects the ability of an atom to hold onto its electrons.
Recall how fluorine acts in the OF₂ molecule.
Using what you've learned about oxidation states, predict the formula for a compound between aluminum (Al) and chlorine (Cl).
Balance the charges to find the right ratio.
Describe how understanding oxidation states can aid in predicting whether a reaction will occur between two elements.
