Reactivity series Flashcards
Do alkali metals react in water?
Yes. Alkali metals react vigorously in water, moving across the surface of the water, fizzing and bubbling (no for lead, copper and gold).
Do alkali metals react with oxygen?
Yes. Alkali metals react with oxygen (no for gold).
Do alkali metals react with acid?
Yes. Alkali metals react with acid (no for copper and gold).
What is the product when alkali metals react in water?
When alkali metals react with water, the product is metal hydroxide.
e.g.
potassium + water - Potassium hydroxide
Can you sort them out according to how large the reaction is with water.
Lithium Sodium Potassium Rubidium Caesium
Caesium Rubidium Potassium Sodium Lithium
Can you arrange the reactive metals Gold Copper Lead Iron Zinc Magnesium Sodium Potassium
Reactive metals Potassium Sodium Magnesium Zinc Iron Lead Copper Gold
Why is magnesium used in a flare?
Magnesium is used in a flare because it burns brightly.
Group 1 reactivity - as you go down the periodic table the reactivity increases or decreases?
Group 1 reactivity increases as you go down the periodic table: Caesium Rubidium Potassium Sodium Lithium
When you burn magnesium, what is the product?
Magnesium oxide
When you heat iron, what is the product?
Iron oxide
When you heat copper, what is the product?
Copper oxide (black)
