You are correct it would be isoelectronic with the Noble Gas, Xe...

Explanation:

And thus elemental iodine, the atom, is a reasonably strong oxidant, and we use the old aufbau principle, and distribute 54 electrons.....

I: 1s22s22p63s23p63d104s24p64d105s25p5.

I: 1s22s22p63s23p63d104s24p64d105s25p6. Are there 54 electrons? If not, there should be.

Of course, we must simply remember that when we use iodine, we work with the diatom, I2, as indeed are all of the halogens.....
