| Question | Answer |
| K Potassium | Na Sodium |
| Ca Calcium | These first three are too dangerous to reactwith acid, they react with water to give their corresponding Hydroxide and Hydrogen |
| Mg Magnesium | Very slow reaction with cold water, reacts quickly with steam |
| Al Aluminium | no reaction with water |
| Zn Zinc | reacts with acid |
| Fe Iron | MASH. Metal+Acid~Salt+Hydrogen |
| Pb Lead | Cu Copper no reaction with water |
| Ag Silver No reaction with acid | Kinky Natalia Can Make Any Zebra Feel Part (of) Cultivated Agriculture |

| Displacement Reactions - a metal is reactive if it combines easily with other elements eg Oxygen, Sulfur -Potassium is very reactive. It is NEVER found uncombined in the earth. It is always found as part of a compound. -Gold is very unreactive. It is often found in the earth uncombined - A reactive metal can displace a less reactive from its compound | EG CuSO4 + Mg ~ MgSO4 + Cu CuSO4 + Fe ~ FeSO4 + Cu |
