Bonds and molecular shape
What students will learn
Connect bonding interactions to electron bookkeeping, molecular geometry and the direction of a molecular dipole.
Before this topic
- Valence electrons and neutral ionic formulas
- Electronegativity and Coulombic attraction
Read and connect
Read: Types of Chemical Bonds →
Compare sharing, ionic character and delocalized metallic electrons using properties as evidence.
Read: Intramolecular Force and Potential Energy →
Read the bond-energy minimum: separate equilibrium distance, dissociation energy and interaction force.
Read: Structure of Ionic Solids →
Represent an extended ionic solid with the correct ratio, charge balance and mobile-charge explanation.
Read: Structure of Metals and Alloys →
Explain metallic conduction and alloy deformation using delocalized electrons and guest-atom positions.
Read: Lewis Diagrams →
Construct Lewis diagrams from an electron budget; check connectivity, local duets/octets and net charge.
Read: Resonance and Formal Charge →
Use formal-charge sums and equivalent resonance contributors without implying alternating molecules.
Read: VSEPR and Hybridization →
Count domains, distinguish electron and atom geometry, and add bond-dipole vectors.
Supporting reading: Molecular Structure of Acids and Bases →
Later application: compare conjugate-base structures to explain acid and base strength.
Before this connection: Acids, bases, and pH: conjugate pairs and proton transfer.
Further study: Molecular Orbital Theory →
Further study: an original comparison of bonding models; molecular-orbital theory does not become a required geometry lesson.
Before this connection: Lewis diagrams, molecular geometry and sigma/pi bonding.
Further study: What is Organic? →
Further study: browse the original introduction to organic classes and functional groups.
Before this connection: Lewis diagrams and carbon bonding.
Further study: Basic Organic Nomenclature →
Further study: original hydrocarbon nomenclature and skeletal representations.
Before this connection: Original introduction to organic classes.
Further study: Advanced Nomenclature →
Further study: original side-chain, functional-group and linkage nomenclature.
Before this connection: Basic organic nomenclature.
Further study: Chemical Properties of Organics →
Further study: original organic-property examples; use the native intermolecular-force and solubility lessons for the reviewed main path.
Before this connection: Intermolecular forces and solution interactions; Basic organic structure and nomenclature.
Check understanding
Use the complete prompt to make student reasoning visible, then consult the separate worked reasoning and criteria. A reading completion tick records reading history.
Construct and justify a Lewis diagram →
Build HCN with a counted electron budget, correct bond orders and a hydrogen-duet explanation.
Connect a created structure to shape and polarity →
Draw NH3 with its lone pair, then compare domain count, geometry, angles and dipole-vector cancellation for three species.
