The electronegativity values for chlorine Cl and oxygen O are 3.16 and 3.44, respectively. To find the electronegativity difference between these two atoms, subtract the smaller value from the larger value:Electronegativity difference = 3.44 O - 3.16 Cl = 0.28To determine if the bond formed between these two atoms is covalent or ionic, we can use the following general guidelines:- If the electronegativity difference is less than 0.5, the bond is considered nonpolar covalent.- If the electronegativity difference is between 0.5 and 1.7, the bond is considered polar covalent.- If the electronegativity difference is greater than 1.7, the bond is considered ionic.Since the electronegativity difference between Cl and O is 0.28, the bond formed between these two atoms is considered nonpolar covalent.
