Remember, prefixes are NOT used for ionic compounds. Compounds that contain covalent bonds (also called molecular compounds) exhibit different physical properties than ionic compounds. Follow the given steps to calculate the electronegativity or chemical bond type: Note the electronegativity of the first and second elements. Transcribed image text: Classify the compound SO_2 as ionic or covalent.

The Oxygen as well as Sulfur are highly electronegative although the Sulfur is not nearly as Oxygen. Ionic solids, such as sodium chloride and nickel oxide, are composed of positive and negative ions that are held together by electrostatic attractions, which can be quite strong (Figure 10.39 . When the distance is increased and the shielding is also increased, it causes a decrease in nuclear attraction. Write the molecular formula for each compound. Polyatomic ions are covalent units (molecules) where the total number of protons \(\neq\) to the total number of electrons and they were introduced in section 2.6.4.2.
