Verified step by step guidance1
Identify the elements present in the compound Cl_2O: chlorine (Cl) and oxygen (O).
Recognize that this is a covalent compound formed between two nonmetals, so we use prefixes to indicate the number of atoms of each element.
Determine the number of atoms of each element: 2 chlorine atoms and 1 oxygen atom.
Apply the appropriate prefixes: 'di-' for 2 chlorines and 'mono-' for 1 oxygen (the 'mono-' prefix is often used for the second element, but the 'o' is usually dropped in 'monoxide').
Combine the prefixes and element names to form the correct name: 'dichlorine monoxide'.
