Question

which formula accurately represents a neutral ionic compound?
choose 1 answer:
a bao
b bamg
c bacl

Explanation:

Step1: Determine the charges of ions

• Barium (\(Ba\)) forms \(Ba^{2+}\) ion.
• Oxygen (\(O\)) forms \(O^{2 -}\) ion.
• Magnesium (\(Mg\)) forms \(Mg^{2+}\) ion.
• Chlorine (\(Cl\)) forms \(Cl^{-}\) ion.

Step2: Check charge neutrality

• For \(BaO\): \(+2+( - 2)=0\).
• For \(BaMg\): \(+2+( + 2)

eq0\).

• For \(BaCl\): \(+2+( - 1)

eq0\).

Answer:

A. \(BaO\)
