What is the reactivity series?
A list of metals arranged in order of decreasing reactivity.
Which metal is at the top of the reactivity series?
Potassium.
True or False: Gold is more reactive than sodium.
False.
Fill in the blank: The reactivity series helps predict how metals will react with _____ and acids.
water.
What is the reactivity order of the following metals from most to least reactive: Calcium, Iron, and Copper?
Calcium, Iron, Copper.
Which metal is less reactive: Aluminum or Lead?
Lead.
Name one use of the reactivity series in practical applications.
To determine which metals can displace others in reactions.
True or False: The reactivity series is the same in all chemical contexts.
False.
What is the general trend in the reactivity series as you move down?
Reactivity decreases.
Which two metals are often used to galvanize steel?
Zinc and Aluminum.
Fill in the blank: The reaction of a metal with an acid produces _____ and a salt.
hydrogen.
What is the reactivity series used to predict?
The outcomes of displacement reactions.
Arrange the following metals in order of reactivity: Magnesium, Silver, Zinc.
Magnesium, Zinc, Silver.
What is the reactivity series also known as?
Activity series.
True or False: Lithium is less reactive than Potassium.
True.
Which group of metals is typically at the bottom of the reactivity series?
Noble metals.
What happens when a more reactive metal displaces a less reactive metal in a compound?
The more reactive metal replaces the less reactive metal.
Fill in the blank: The reactivity series is important in _____ for extraction of metals.
metallurgy.
Name a metal that is often used in batteries due to its reactivity.
Lithium.
What is the position of Iron in the reactivity series?
It is moderately reactive.
Which metal is used to make jewelry due to its low reactivity?
Gold.
True or False: The reactivity series can change based on the conditions of the environment.
True.
What type of reactions can be predicted by the reactivity series?
Single displacement reactions.
Fill in the blank: The reactivity series is used to determine the _____ of metals in reactions.
strength.
Which metal is used in the extraction of aluminum?
Bauxite (but aluminum itself is extracted from bauxite through electrolysis).
What is the main factor that affects the position of metals in the reactivity series?
Their ability to lose electrons.
