Reactivity Series of Metals

Question-and-Answer flashcards covering the relative positions and implications of the metals listed in the reactivity series.

What metal is at the top of the provided reactivity series?

Potassium (K)

Which two alkali metals occupy the first and second positions in the series?

Potassium (K) and Sodium (Na)

How does metal reactivity change as you move from Potassium down to Gold in the list?

Reactivity decreases

Arrange Magnesium (Mg), Aluminium (Al), and Zinc (Zn) in order of decreasing reactivity.

Magnesium (Mg) > Aluminium (Al) > Zinc (Zn)

Which metal is listed immediately below Zinc (Zn) in the series?

Iron (Fe)

Name one metal from the list that can displace hydrogen from dilute acids.

Zinc (Zn) (any metal above hydrogen such as Fe, Zn, Al, etc., would be correct)

Which metals in the series are less reactive than hydrogen?

Copper (Cu), Mercury (Hg), Silver (Ag), and Gold (Au)

What is the least reactive metal mentioned in the notes?

Gold (Au)

Where is Hydrogen placed in the provided reactivity series relative to metals?

Between Lead (Pb) and Copper (Cu)

Why is Hydrogen included in the reactivity series of metals?

It serves as a reference point; metals above it can displace hydrogen from acids, while those below cannot
