Intermediate
Chemical Bonding
Model how atoms transfer or share electrons to form ionic and covalent substances, then connect bonding to formulas and properties.
Learning outcomes
- Predict ionic bonding between metals and nonmetals
- Predict covalent bonding between nonmetals
- Use valence electrons to explain simple formulas
- Compare properties of ionic and molecular substances
Visual notes
Ionic bonds form through electrostatic attraction after electron transfer.
Covalent bonds form when atoms share electron pairs.
Formula ratios keep total charge neutral in ionic compounds.
