Atoms combine and bond to each other to make molecules. A molecule is made up of a certain number and type of atom. For example, water (H 2 O) is always made from two hydrogen atoms and one oxygen ...

Remind students that the oxygen-hydrogen (O–H) bonds in water make it a polar molecule. This polarity makes water molecules attracted to each other. Explain that the oxygen–hydrogen (O–H) bond in the ...
