Verified step by step guidance1
Understand the naming convention: 'iodine monochloride' indicates a compound made of iodine and chlorine atoms, with 'mono-' meaning one chlorine atom is present.
Identify the elements involved: iodine (I) and chlorine (Cl). Since 'monochloride' specifies one chlorine atom, the formula must contain exactly one Cl atom.
Determine the number of iodine atoms: since no prefix is given before iodine, it implies one iodine atom in the compound.
Combine the atoms to write the chemical formula: one iodine atom and one chlorine atom gives the formula \(\text{ICl}\).
Verify the options given and confirm that \(\text{ICl}\) matches the correct formula for iodine monochloride.
