Metals & The Reactivity Series Flashcards
What are state symbols?
Symbols that determine the state of a chemical/element.
What does the state symbol (l) mean?
Liquid
What does the state symbol (g) mean?
Gas
What does the state symbol (aq) mean?
Aqueous Solution (dissolved in water)
What is the word equation for the oxidation of magnesium?
magnesium + oxygen —> magnesium oxide
Balance this chemical equation:
Al + O₂ → Al₂O₃
4Al + 3O₂ → 2Al₂O₃
Describe the typical properties of elements that are metal.
5 main properties
- malleable
- ductile
- able to conduct electricity
- able to conduct heat
- solid at room temperature
Describe the main properties of elements that are not metals.
4 main properties
- brittle
- coloured
- not able to conduct electricity
- not able to conduct heat
Why is graphite (a form of carbon) a unique non-metal element?
Why is mercury a unique metal element?
What is unusual about iodine?
What is sublimation?
Describe and explain why:
- Gold is used in jewellery
- Aluminium is used in aircraft bodies
Why wouldn’t you use:
- Sodium to build a bridge
- Gold to make nails
What is an oxidation reaction?
Describe how lithium reacts with water.
Describe how sodium reacts with water.
Describe how potassium reacts with water.
Describe how calcium reacts with water.
Describe how magnesium reacts with water.
Describe how aluminium reacts with water.
Describe how zinc reacts with water.
Describe how iron reacts with water.
Explain why some metals do not reacts with oxygen, water or acids in terms of their positions on the reactivity series.
