\[ [\ddot{\mathbf{O}}=\ddot{\mathrm{N}}-\ddot{\mathbf{O}}:]^{-} \] The Lewis structure of an ion is given above. Answer the following questions for this ion. a) What is the total number of electrons in the Lewis structure? (5 pts) (Write only the result. No explanation is required.) b) Determine the formal charge on the \( (\underline{Q}) \) atom that has single bond. ( 8 pts) (Show your computation; don't just write the result.) c) How many electron groups does the central atom have? (4 pts) (Write only the number. No explanation is required.) d) Write the name of the electron-group geometry. ( \( 5 \mathrm{pts} \) ) e) Write the VSEPR notation. (3 pts) f) Write the name of the molecular shape. (5 pts)
