Bond length is the distance between the centers of two bonded atoms. On the potential energy curve, the bond length is the internuclear distance between the two atoms when the potential energy of the system reaches its lowest value. Given that the atomic radii of H and I are 25.0 pm and 133 pm , respectively, predict the bond length of the HI molecule.

Answer:

158.0 pm

Explanation:

In this case, the bond length of the HI molecule is equal to the sum of the atomic radii of its components. Which is to say:

Bond length HI = Atomic Radius H + Atomic Radius I

Bond Length = 25.0 pm + 133 pm

Bond Length = 158.0 pm
