In a magnesium oxide unit, the distance between the magnesium ion (Mg2+) and the oxide ion (O2−) is 2.13×10-10 m. Calculate the work required to separate the two ions to an infinite distance apart. (Model the ions as point charges at rest before and after the separation.) If you could do this without using Calculus that would be great.

1. In class, we calculated the electrostatic force between sodium and chlorine ions in NaCl, which is an example of an ionic bond Another type of chemical bond is a covalent bond, where electrons are shared between atoms, like in a hydrogen molecule, H2. We can try to model this as a collection of three charges, with the two nuclei treated like two +e charges, and the two electrons treated as one -2e charge. (20 points) If the electrons are...
