SUMMARY
The Lewis structure for iodine trifluoride (IF3) requires a total of 32 electrons, derived from the 7 valence electrons of iodine and 7 from each of the three fluorine atoms. The initial calculation indicates 4 bonding pairs, suggesting 2 bonds, but the correct interpretation reveals that octet fulfillment is not mandatory for all atoms in this molecule. The final structure confirms that IF3 can exist with iodine having fewer than 8 electrons, which is a common occurrence in compounds involving heavier elements.
