What type of bond exists in a molecule of hydrogen iodide and what is the electronegative difference

Polar covalent bond, with a electonegative of 0.46

Explanation:

Hydrogen iodide (HI)is a diatomic molecule formed with covalent bonds between hydrogen and iodine atoms.  The molecule is a dipole since it has two electrical poles, the electron cloud is denser in one side. The electrons are not equally shared this type of bond is known as a polar covalent bond. This happens due to the difference in electronegativity, the bigger the difference the more polar will be the bond. Iodine has an electronegativity of 2.66 while hydrogen has a value of 2.2. The difference in electronegativity is 0.46 the strength is fairly enough to have a slightly polar character, thus the electron cloud is in the Iodine side.

a polar covalent bond, with a electonegativity difference between 0 and 1.7

Explanation:

from Chemistry castle learning

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
