which substance is an ionic compound?

n₂o

xe

sri₂

bh₃

Explanation:

• Ionic compounds are formed by the transfer of electrons from a metal to a non - metal.
• \(N_2O\) is a covalent compound as it is formed by the sharing of electrons between non - metals (nitrogen and oxygen).
• \(Xe\) is a noble gas and exists as individual atoms, not as a compound.
• \(SrI_2\) is an ionic compound. Strontium (\(Sr\)) is a metal (in group 2 of the periodic table) and iodine (\(I\)) is a non - metal. Strontium donates electrons to iodine to form \(Sr^{2 + }\) and \(I^-\) ions, which are held together by ionic bonds.
• \(BH_3\) is a covalent compound. Boron (\(B\)) and hydrogen (\(H\)) are non - metals and share electrons.

Answer:

\(SrI_2\)
