The reactivity order of Cu, Ag ,Au is

The order of reactivity of K, Mg, Au and Zn with water is

Assertion : The order of atomic radii of Cu, Ag and Au is Cu lt Ag ~~ Au . Reason : The atomic radii of 4d series elements are larger than those of 3d series elements but generally the radii of 4d and 5d series elements are almost identical.

The melting points of Cu, Ag and Au follow the order

Arrange the following metals in the decreasing order of chemical reactivity : Cu, Mg , Fe,Ca,Zn

What would be the correct order if Zn, Fe, Al and Cu are arranged in increasing order of reactivity?

The correct order of reactivity of K,Mg,Zn and Cu with water according to the electrochemical series is

The order of reactivity is
