Question

You are given samples of 3 metals sodium magnesium and copper. Suggest any 2 methods to arrange them in order of decreasing reactivity

Answer 1

Method 1 : By Studying Trend :-

By Studying trends in the modern periodic table for chemical reactivity, chemical reactivity decreases from left to right in a period and increases down the group, we can conclude that,

Na > Mg > Cu

Method 2 : By studying Reactivity Series :-

In reactivity series, metals are placed in decreasing order of chemical reactivity.

These metals are placed in the order of :-

Na > Mg > Cu
