Which element is a gaseous non-metal?

Answer and explanation

Correct answer: Nitrogen

Nitrogen is a gas at ordinary temperature and pressure and is a non-metal, so nitrogen is correct. However, oxygen and chlorine are also gaseous non-metals, so the given question has more than one correct option. Exam tip: in such questions, check both the physical state and classification of every option; a valid MCQ should contain only one correct answer.
