Hydrogen has a atomic number 1,thus, it's electronic configuration is 1s1,while the electronic configuration of Iodine is 5s2 5p5 as the atomic number of Iodine is 53.
Thus, Hydrogen and Iodine both have 1-1 unshared electron.
Therefore, Hydrogen and Iodine will form a covalent bond by sharing unpaired electron in it.
So, Hydrogen Iodide has no unshared pair of electron.

If you consider HI to be a covalent compound, then you have 7 valence electrons in I, and 1 in H. A covalent bond formed between the two atoms takes up the 1 valence electron from H, and one of the 7 from I. This leaves you with 6 electrons, ie 3 pairs.
