Chemistry · Grades 9–12
Bonding, shape and polarity · Revision sheet
Separate bond polarity from the polarity of a whole molecule.
Learn the idea
Covalent bond
A simple covalent bond model describes shared electron density between atoms.
Electron domains
For introductory VSEPR, electron domains around a center influence geometry; lone pairs also matter.
Polarity
A molecule’s net dipole depends on both bond dipoles and geometry.
Conditions
The simple shape model is a useful approximation, not a literal stationary picture of electrons.
Explain without looking
- Why must lone pairs be considered when predicting a molecular shape?
- Which question is about a molecule rather than a bond?
