Verified step by step guidance1
Identify the definition of a molecular element: A molecular element is a chemical element that naturally exists as molecules, typically consisting of two or more atoms of the same element bonded together.
Review the list of options provided: water, iron, nitrogen, NaCl, and potassium.
Determine the chemical composition of each option: Water (H₂O) is a compound, iron (Fe) is a metallic element, nitrogen (N₂) is a diatomic molecular element, NaCl is a compound, and potassium (K) is a metallic element.
Recognize that nitrogen (N₂) is a diatomic molecule, meaning it consists of two nitrogen atoms bonded together, which fits the definition of a molecular element.
Conclude that among the given options, nitrogen is the only molecular element, as it naturally exists as N₂ molecules.
