medium Q15 of 15
Step-by-Step Solution
Step 1: Understand the reactivity series of metals
Potassium is an alkali metal and is the most reactive metal, placed at the top of the reactivity series.Step 2: Compare with other metals
Iron, copper, and gold are less reactive; gold is least reactive and found at the bottom.Final Answer:
Potassium → Option CQuick Check:
Most reactive metal = Potassium ✅
Quick Trick: Use mnemonic: 'Please Stop Calling Me A Cute Zebra...' for reactivity order.
Common Mistakes:
- Confusing gold or copper as highly reactive metals.
