Using the VSEPR model, the electron geometry of the central atom in no3- is trigonal planar geometry.
The valence shell electron pair repulsion (VSEPR) theory is a model used generally to predict 3-D molecular geometry based on the number of valence shell electron bond pairs among the atoms in a molecule or also in ion. This model assumes that electron pairs will arrange themselves to minimize repulsion effects from one another and then ultimately form a specific geometry.
In the case of NO3-, the trigonal planar geometry is found. The central atom N has no lone pair left, all three bonds count for only one bonding pair each. Also the double bond here counts for only one bonding pair, just like the single bond. From this we can predict that the geometry here is trigonal planar.
