A model for NO2- is shown in the chem3D window. NO2- has bent geometry. This geometry is sometimes called angular or V-shaped geometry.Rotate the molecule until you have a feeling for its three-dimensional shape. How many atoms are bonded to the central atom? fill in the blank 1 Consider the bond angle at the central atom. What is the approximate numerical value of this angle? degrees. You could view this geometry as being derived from a trigonal planar molecule by removing one atom, or as being derived from a tetrahedral molecule by removing two atoms. Which does the bond angle suggest? For practice, type in the name of the geometry of the molecule: fill in the blank 4
