Question

Arrange potassium (K); sodium (Na); copper (Cu); and silver (Ag) in decreasing order of their reactivity?

( A )  Potassium (K) > Sodium (Na) > Copper (Cu) > Silver (Ag)

( B )  Copper (Cu) > Sodium (Na) > Silver (Ag) > Potassium (K)

( C )  Potassium (K) < Sodium (Na) < Copper (Cu) < Silver (Ag)

( D )  Silver (Ag) > Potassium (K) > Sodium (Na) > Copper (Cu) ​

Answer 1

Answer:

Potassium (K) > Sodium (Na) > Copper (Cu) > Silver (Ag)

Explanation:

Reactivity of metals can be understand using reactivity series.

Answer 2

( A )  Potassium (K) > Sodium (Na) > Copper (Cu) > Silver (Ag)

Reactivity of metels can be understand by reactivity series.
