Verified step by step guidance1
Step 1: Understand the problem is asking for the correct chemical formula of chlorine dioxide, which is a compound consisting of chlorine and oxygen atoms.
Step 2: Recall that the name 'chlorine dioxide' indicates the presence of one chlorine atom and two oxygen atoms, as 'dioxide' means two oxygen atoms.
Step 3: Write the chemical formula by placing the chlorine symbol (Cl) followed by the oxygen symbol (O) with the subscript 2 to indicate two oxygen atoms, resulting in ClO_2.
Step 4: Compare the given options to the correct formula ClO_2 to identify the correct choice.
Step 5: Confirm that ClO_2 matches the name chlorine dioxide, while other options like ClO, Cl_2O, and Cl_2O_2 do not correspond to the correct stoichiometry.
