Shape of IF7 Molecule

The shape of the IF7 molecule is pentagonal bipyramidal.

Explanation:

To understand the shape of the IF7 molecule, let's first look at its Lewis structure.

IF7 has 7 valence electrons in the outermost shell of the iodine atom and 1 valence electron from each of the 7 fluorine atoms. This gives a total of 14 valence electrons for the molecule.

To draw the Lewis structure, first, we place the iodine atom in the center and surround it with the 7 fluorine atoms. Each fluorine atom forms a single bond with the iodine atom. This uses up 7 of the 14 valence electrons.

Next, we place the remaining 7 electrons as three lone pairs on three of the seven fluorine atoms.

The resulting Lewis structure shows that the IF7 molecule has a pentagonal bipyramidal shape.

This means that the molecule has a central iodine atom with five surrounding fluorine atoms arranged in a pentagonal shape around the central iodine atom. The remaining two fluorine atoms are located above and below the pentagon.

Overall, the IF7 molecule has a symmetrical shape and is considered to be a highly polar molecule due to the electronegativity difference between the iodine and fluorine atoms.
