Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Identify the Elements
- Oxygen (O) is a nonmetal - Barium (Ba) is a metal (specifically an alkaline earth metal)
Step 3:: Determine Electron Configuration
- Barium: $$Ba \rightarrow Ba^{2+}$$ (loses 2 electrons)
- Oxygen: O \rightarrow O^{2 -} (gains 2 electrons)
Step 4:: Check Ionic Bonding Criteria
- Metals typically form positive ions - Nonmetals typically form negative ions - Opposite charges attract, forming ionic compounds
Step 5:: Write the Ionic Compound Formula
- Balanced formula: $$BaO
- Oxygen gains 2 electrons: O^{2 -}
Final Answer
Yes, oxygen and barium form an ionic compound with the chemical formula BaO (barium oxide), which is a stable ionic compound where barium transfers two electrons to oxygen, creating a neutral ionic bond.
