| hydrogen bond | Weak attraction between a hydrogen atom and another atom. |
| covalent bond | Type of bond between atoms in which the electrons are shared. |
| acid | Solution with a pH of less than 7 and forms hydrogen ions (H+). |
| base | Solution with a pH more than 7 and produces hydroxide ions (OH-). |
| pH scale | Used to measure the concentration of H+ ions in a solution. |
