The less reactive metal (a) K
,Na (b) Zn, Al (c) gold and silver
Answers
Answer:
The order of intensity of reactivity is known as reactivity series. Reactivity of element decreases on moving from top to bottom in the given reactivity series.
In the reactivity series, copper, gold, and silver are at the bottom and hence are least reactive. These metals are known as noble metals. Potassium is at the top of the series and hence is most reactive.
Reactivity of some metals are given in descending order
K > Na > Ca > Mg > Al > Zn > Fe > Pb > Cu

✰ཽThey're really not "non-reactive", gold and silver certainly appear in a variety of complexes, but they are highly resistant to corrosion and oxidation, which is what makes them far less reactive with typical reagents than most metals.*
