Verified step by step guidance

Identify the chemical properties of each element mentioned in the problem: Iron, Sodium, Helium, and Chlorine.

Recall that Iron (Fe) can react with oxygen and moisture to form iron oxide, commonly known as rust. This is a correct association.

Understand that Sodium (Na) is an alkali metal known for its high reactivity with water, producing sodium hydroxide and hydrogen gas. This is also a correct association.

Review the properties of Helium (He), which is a noble gas. Noble gases are characterized by their lack of reactivity due to having a full valence electron shell. Therefore, the statement that Helium is highly reactive is incorrect.

Recognize that Chlorine (Cl) is indeed a strong oxidizing agent, meaning it readily gains electrons in chemical reactions. This is a correct association.
