comparing reactivity of different metals\nrank the metals from most reactive (1) to least reactive (3).\nsilver:\nstrontium:\ntechnetium:

Answer

Explanation:

Step1: Recall metal - activity series

Based on the metal - activity series, strontium is a highly reactive alkaline - earth metal. Technetium is a transition metal with moderate reactivity. Silver is a relatively unreactive metal among these.

Step2: Rank the metals

Strontium is the most reactive, followed by technetium, and then silver.

Answer:

Silver: 3 Strontium: 1 Technetium: 2
