The sum of lone pairs present on the central atom of the interhalogen IF 5_5 and IF 7_7 is _________

Step-by-Step Verified Solution

Interhalogen compounds are the substances that consist of two different halogens. The most common type of interhalogen compounds are binary, containing only two different elements.

In IF 5_5 , iodine (I) is the central atom. Iodine has 7 valence electrons, 5 of which are used for bonding with the 5 fluorine (F) atoms. This leaves 2 electrons, or 1 lone pair on the iodine atom.

In IF 7_7 , iodine (I) is the central atom again. Iodine has 7 valence electrons, all of which are used for bonding with the 7 fluorine (F) atoms. So, there are no lone pairs on the iodine atom.

Therefore, the sum of lone pairs present on the central atom of the interhalogens IF 5_5 and IF 7_7 is 1.
