| Question | Answer |
| What is an alloy? | A metal made by combining two or more metallic elements |
| What does malleable mean? | Able to be bent, rolled into sheets and shaped without them breaking. |
| What does ductile mean? | Able to be drawn out into wires. |
| What does sonorous mean? | The metal makes a ringing noise when hit. |
| What does magnetic mean? | It has the power to attract. |
| What does dull mean? | Dark, has no excitement, opposite of shiny. |
| What is a metal? | A solid material which is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity |
| What is a non-metal? | An element or substance that is not a metal. |
| What clues can we use to see a chemical reaction? | Bubbles of gas being giving off A change in temperature A colour change A change in mass. |
| What is at the top of the reactivity series? | Potassium. |
| What is at the bottom of the reactivity series? | Platinum. |
| How many elements are in the reactivity series? | 15. |
| What is a Displacement reaction? | Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound. |
| What is the reactivity series? | A reactivity series is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their "reactivity" from highest to lowest. |
| What is oxidation? | The process or result of oxidizing or being oxidized. |
| What is an acid? | A substance with a pH less than 7. |
| What does corrosive mean? | That the acid can destroy skin and attack metals. |

| What is an alkali? | A substance with a pH over 7. |
| What pH is neutral on the pH scale? | 7. |
| What does universal indicator do? | Tells us what pH a substance is. |
| What is neutralisation? | If we add a certain amount of acid to an alkali or a certain amount of alkali to an acid the substance will become neutral at a pH of 7. |
| What is titration? | A titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution. |
| What is an antacid? | (Chiefly of a medicine) preventing or correcting acidity, especially in the stomach. |
| What is correlation? | The degree of linear relationship between two variables. |
| What does repeatable mean? | Able to be done again. |
