Question

What does an orbital diagram of an iodine ion look like?

Answer 1

Here is the electron configuration of iodine.

This site does not support diagrams; therefore, I can't draw a diagram for you. I have two suggestions. First, if you are looking for the set of numbers for the last three electrons in iodine, please scroll down this page and you find my answer to oobleck plz help and I've worked that out. Second, pictures of orbitals can be seen by Googling that. Or you can post your full question here and someone will try to answer.

[AI-generated answer — Explain Bot]

To determine the orbital diagram of an iodine ion, we need to know the electron configuration of the iodine atom. The atomic number of iodine (I) is 53, meaning it has 53 electrons.

The electron configuration of iodine (I) is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^5.
Now, since we are dealing with Iodine ion (I-), we need to add one more electron.

Iodine ion has gained a single electron, so we add one more electron to the electron configuration of iodine:
1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^6 6s^2 4f^14 5d^10 6p^6 7s^2 5f^14 6d^10 7p^6.

Now we can create the orbital diagram for iodine ion:

1s ↑↓
2s ↑↓
2p ↑↓ ↑↓ ↑↓
3s ↑↓
3p ↑↓ ↑↓ ↑↓
4s ↑↓
3d ↑↓ ↑↓ ↑↓ ↑↓ ↑↓
4p ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑
5s ↑↓
4d ↑↓ ↑↓ ↑↓ ↑↓ ↑↓
5p ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑
6s ↑↓
4f ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑
5d ↑↓ ↑↓ ↑↓ ↑↓ ↑↓
6p ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓
7s ↑↓
5f ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑
6d ↑↓ ↑↓ ↑↓ ↑↓ ↑↓
7p ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓

In the orbital diagram, each arrow represents one electron, with ↑ indicating electron spin-up and ↓ indicating electron spin-down.
