    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...
