Question

What is the charge associated with each side of the HI molecule?
Express your answer in Coulombs.

Answer 1

Hey @pezpez10 and welcome to Openstudy.

Do you have some additional information with your question? From the question you write there, i see no other option than starting to do approximation for the determination of the wave function and the energy in a quantum mechanical manner.

Answer 2

Any chance you are for example given a dipole moment of the molecule along with a distance between the center of the atoms? in the case we can easily calculate the atomic charge for a diatomic molecule.

Answer 3

hey do you get this at all

Answer 4

This was the previous question.
The distance between the atoms of H−I is 1.61Å. What is the distance in meters?
Answer: r=1.61*10^(-10) m

Answer 5

Oh, and the dipole movement of HI is 1.4*10^(-30)Coulomb-meters

Answer 6

That gives me something to work with! :)
In that case we can use the dipole moment to calculate the atomic charge:
\[\Large Q=\frac{ \mu }{ r }\]
Here is \(Q\) the atomic charge, \(\mu\) the dipole moment and \(r\) the distance between the atoms.

Make sure the units cancel out so you get the unit coulomb for the atomic charge.

When you do this calculation you would get a positive number which correspond to the hydrogen, the atomic charge of Iodide would then be the negative due to the system being uncharged.
