You want to make a “force field” that will keep air molecules out of a certain region of space. This “force field” will be some voltage difference that the air molecules would have to cross. Assume that one electron is stripped from each molecule of air. What is the ∆V required for this force field to work at sea-level (one side vacuum, one side air) at 20 ◦C?

Atoms can bond to other atoms to make molecules. Atoms sometimes break these bonds and form them in a different way. For example, it is possible to take two molecules of hydrogen (H_2) and one molecule of oxygen (O_2), put them near one another, give them a little spark to help them start a reaction, and you will end up with two molecules of water (H_2O). Do you see what happened? Some of the H-H bonds and the O-O bonds...
