- C4 - Chemical Changes - The Reactivity Of Metals
- Metal + Water ---> Metal Hydroxide + Hydrogen Bubbles
- React With Water
- Potassium
- Sodium
- Lithium
- Calcium
- Untitled
- React Slowly With Hot Water
- Magnesium
- Zinc
- Iron
- Do Not React With Water
- Copper, Silver & Gold
- Example
- Sodium + Water --------> Sodium Hydroxide + Hydrogen
- React With Water
- Metal + Acid ----->Metal Salt +Hydrogen
- Extremely Violent Reactions
- Potassium, Sodium, Lithium
- React with Acids to form salt +H2 gas
- Calcium, Magnesium, Zinc, Iron
- Do not react with acits
- Copper, Silver. Gold
- Metal tends to disappear or dissolve
- Hydrogen in the form or bubbles or fizzing
- EXAMPLE
- Zinc + Hydrochloric Acid -----> Zinx Chloride +Hydrogen
- Extremely Violent Reactions
- Untitled
- Summary
- HIGH REACTIVITY
- Aluminium, Calcium, Sodium, Potassium (GROUPs 1, 2, 3 metals
- Medium Reactivity
- Copper, Iron, Tin, Zinc (More reactive transition Metals)
- LOW REACTIVITY
- Gold, Plantinum, Silver (Less Reactive Transition Metals
- Used for Jewellery
- Gold, Plantinum, Silver (Less Reactive Transition Metals
- Keywords
- Displacement
- When a more reactive element takes the compound away from a less reactive element, this commonly happens with the group 7 halogens and with metals
- Extraction
- Is a method used to obtain a pure metal (Usually from its ore)
- Reactivity
- Is how quickly and vigorously an element reacts. Low Reactivity elements will not react with many other substances and reactions will happen very quickly
- Oxidation
- When a Substance Gains Oxygen
- Displacement
- HIGH REACTIVITY
- Metal + Oxygen -------> Metal Oxide
- Example
- Magnesium + Oxygen -----> Magnesium Oxide
- OXIDATION REACTION
- React with Oxygen very vigorously at room temperation
- Potassium, Sodium, Lithium
- React with Oxygen very slowly at room temperature or much faster when heated
- Calcium, Magnesium, Zinc, Iron, Copper, SIlver
- Metals that do not react with oxygen
- Gold
- Example
- Metal + Water ---> Metal Hydroxide + Hydrogen Bubbles
