| Acid | below 7 on the pH scale, contains hydrogen ions |
| Base | above 7 on the pH scale, contains hydroxide ions |
| ion | an element that has gained or lost an electron and is charged. Like H+ |
| element | Only one type of atom, one capital letter. |
| compound | two or more types of atoms, two or more capital letters. |
| electron | negatively charged sub atomic particle. |
| proton | positively charged sub atomic particle. |
| neutron | located in the nucleus of an atom and has no charge. |
| single replacement reaction | We used this type of reaction to produce hydrogen gas in the chemistry lab. |
| valence shell | The outer most shell of an atom. |
| octet rule | All element want 8 electrons in their valence shell so they will be stable. |
| lithium chloride | LiCl |
| ionic bond | The transfer of electrons causing the formation of a compound. |
| covalent bond | The sharing of electrons to form molecular compounds. |
| ionic compound | A compound made from a metal and a non-metal. |
| molecular compound | A compound made from two non-metals. |
| exothermic reaction | A reaction that gives off heat. |
| red stair case | Separates the metals from the non-metals on the periodic table. |
| oxidation number | Shows how many electrons are gained or lost when an element reacts with another element to form a compound. |
| titration | Neutralizing Two acids with a common base and expressing the relationship as a ratio. |
