Write the expected ground-state electron configuration for the element with one unpaired 5p electron that forms a covalent compound with fluorine.

Iodine:

Electron configuration:

[Kr]4d10 5s2 5p5

1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p5

Explanation:

Iodine is an element in group 17. It has only on umpired electron in the 5p orbital it combines with fluorine which also has one unpaired electron in its outermost orbital to form different complex interhalogen compounds by covalent bonding. These interhalogen compounds exhibit various shapes and properties.
