Examples of Acid and Base Based on Louis definition ​

An example is the reaction of ammonia with boron trifluoride. Figure 2. Ammonia and boron trifluoride. Boron trifluoride is the Lewis acid, while ammonia is again the Lewis base. As there is no hydrogen ion involved in this reaction, it qualifies as an acid-base reaction only under the Lewis definition.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
