Nitrogen (N), oxygen (O), chlorine (Cl), neon (Ne), and argon (Ar) are all gases at room temperature. Using the periodic table, which pair of gases do you predict has the most similar properties, and why? Nitrogen and oxygen, because they are both atmospheric gases
Oxygen and chlorine, because they are both halogens
Chlorine and neon, because they are both metalloids
Neon and argon, because they are both noble gases
