Worksheet 13 molecular shapes the shapes of molecules can be predicted from their lewis structuresby using the vsepr valence shell electron pair repulsion model which states that electron pairs around a central atoms will assume a geometry that keeps them as far apart from each other as possible.

Revised ab 5 30 13 labrake vanden bout 2013. The molecular geometry main shapes are tetrahedral trigonal planar trigonal pyramidal bent and linear and are named by measuring the bond angles between the central atom and another atom bonded to it. To learn more about vsepr theory and molecule shapes review the lesson that covers the following objectives.
What s with all these shapes. There are lone pairs on x or other atoms but we don t care. Molecular shape and vsepr theory molecule total valence electrons lewis structure steric number electron group geometry molecular geometry hybridization ex.

Teach your students about vsepr theory and molecular geometry using this great detailed worksheet this worksheet guides students through the following topics in simple terms what does vsepr theory tell us how can we identify the molecular geometry of a molecule given its lewis structure what are t. Vsepr guidelines for using vsepr theory with lewis structures 1 an electron group consist of either a single bond a double bond a triple bond or a lone pair of electrons with each counting as one group.
The valence shell electron pair repulsion vsepr theory or vesper for short is how the geometry of a molecule is determined around a central atom. Total domains generic formula picture bonded atoms lone pairs molecular shape electron geometry. Let s practice assigning hybridization electron domain geometry and molecular geometry.
This worksheet will introduce your students to molecular geometry and how vsepr theory predicts the shapes of compounds.
