What is the steric number and electron geometry of SO2? Refer to the electron geometry table below.Įxamples: Use the electron geometry table to determine the steric number and electron geometry of each molecule. This means you count up the lone pairs and number of atoms attached to the central atom into one number (the steric number) and from there determine electron geometry. You also treat double and triple bonds as one group instead of 3 just like you did in molecular shape. However, with electron geometry (steric number) lone pairs and bonds are treated the same. ![]() In molecular shape (molecular geometry) you treat the electron’s lone pairs and the bonds as two different and separate things. Explore molecule shapes by building molecules in 3D How does molecule shape change with different numbers of bonds and electron pairs Find out by adding single, double or triple bonds and lone pairs to the central atom. ![]() Get the free view of Chapter 5, Chemical Bonding Chemistry 11th Standard Maharashtra State Board additional questions for Mathematics Chemistry 11th Standard Maharashtra State Board Maharashtra State Board,Īnd you can use to keep it handy for your exam preparation.What is the difference between electron geometry (electron domains / electron clouds / steric number) and molecular shape (molecular geometry)?īoth are very similar, but the difference is in how we treat that electron’s lone pairs versus the bonds.
