Imagine that a water molecule is made of two positively charged
hydrogen atoms, each with charge +q, and one negatively charged
oxygen atom, with charge –2q. These atoms are arranged as shown.
The magnitude of the electron charge q = 1.6 x 10^19 C and the
distance unit used in the diagram, “pm”, is picometers, or 10^-12
m. How much energy would it take for you to completely remove the
positively charged hydrogen atom on the left from this molecule,...
