Multiple Choice

Which of these pairings of elements and their chemical properties is incorrect?

Chlorine - Strong oxidizing agent

Iron - Prone to rusting in moist air

Helium - Forms stable compounds easily

Sodium - Highly reactive with water

Verified step by step guidance

Step 1: Understand the chemical properties of each element mentioned in the problem. Chlorine is known to be a strong oxidizing agent, which means it readily accepts electrons from other substances during chemical reactions.

Step 2: Consider the properties of iron. Iron is prone to rusting, especially in the presence of moisture and oxygen, due to the formation of iron oxide.

Step 3: Evaluate the properties of helium. Helium is a noble gas, characterized by its lack of reactivity due to having a complete valence electron shell. It does not easily form stable compounds.

Step 4: Analyze the reactivity of sodium. Sodium is an alkali metal, known for its high reactivity with water, producing hydrogen gas and sodium hydroxide.

Step 5: Identify the incorrect pairing. Based on the properties discussed, the statement 'Helium - Forms stable compounds easily' is incorrect because helium is inert and does not readily form compounds.
