Question

1. which of the following answers contain the elements that are diatomic in nature? hydrogen, helium, neon, argon, krypton, xenon, radon nitrogen, oxygen, fluorine, neon, argon, krypton, hydrogen nitrogen, chlorine, fluorine, carbon, oxygen, bromine, argon oxygen, fluorine, chlorine, bromine, nitrogen, hydrogen, iodine

Explanation:

Step1: Recall diatomic elements

Diatomic elements are elements that exist as two - atom molecules in their natural state.

Step2: Check each option

• Option 1: Helium, Neon, Argon, Krypton, Xenon, Radon are noble gases and are monatomic. So this option is wrong.
• Option 2: Neon, Argon, Krypton are noble gases (monatomic). So this option is wrong.
• Option 3: Carbon is not a diatomic element in its natural state (e.g., carbon exists as graphite or diamond with a different structure), Argon is a noble gas (monatomic). So this option is wrong.
• Option 4: Oxygen (\(O_2\)), Fluorine (\(F_2\)), Chlorine (\(Cl_2\)), Bromine (\(Br_2\)), Nitrogen (\(N_2\)), Hydrogen (\(H_2\)), Iodine (\(I_2\)) are all diatomic in nature.

Answer:

Oxygen, Fluorine, Chlorine, Bromine, Nitrogen, Hydrogen, Iodine
