The bond type in radium oxide (RaO) is ionic. Step 1: Identify the elements involved. Radium (Ra) is an alkaline earth metal, and Oxygen (O) is a nonmetal. Step 2: Determine the electronegativity difference. Metals like radium have low electronegativity and tend to lose electrons, while nonmetals like oxygen have high electronegativity and tend to gain electrons. The large difference in electronegativity between radium and oxygen indicates an ionic bond. Step 3: Describe the bond formation. Radium loses two electrons to form a positive ion (Ra²⁺), and oxygen gains two electrons to form a negative ion (O²⁻). These oppositely charged ions are held together by electrostatic attraction, forming an ionic bond. 3 done, 2 left today. You're making progress.
