A simple procedure for writing

**Lewis structures**is given in a previous article entitled**“Lewis Structures and the Octet Rule”**. Relevant worked examples were given in the following articles: Examples #1, #2, #3 , #4, #5, #6, #7, #8, #9, #10, #11, #12, #13, #14, #15, #16, #17, #18, #19, #20, #21, #22, #23, #24, #25, #26, #27, #28 and #29.
Let us consider the case of the N

_{2}F^{+}cation:__Step 1__: Connect the atoms with single bonds.

__Step 2__: Calculate the # of electrons in π bonds (multiple bonds) using

**formula (1)**:

Where n in this
case is 3 since N

_{2}F^{+ }consists of 3 atoms.
Where V = (2*5 +
7 ) - charge = 17 – 1 = 16

Therefore, P = 6n
+ 2 – V = 6 *3 + 2 – 16 = 4

**Therefore, there are: 1) either 2 double bonds 2) or 1 triple bond**Fig. 2: Lewis electron dot structures for the N_{2}F^{+}^{ }ion. The least plausible
structures are #1 (adjacent + charges ) and #3
(large charge separation). |

Therefore, three plausible

**electron dot structures**were drawn for the N_{2}F^{+}ion.
