OA. BaCl2
The statement, that describes a compound is held together by ionic bonds is "BaCI2" What is an ionic bond?
lonic bonding is a type of chemical interaction in which one atom loses and acquires valence electrons from another.
An ionic bond is established when a metal and a nonmetal combine. Ionic compounds (or salts) are compounds made up of ions, and their constituent ions are bound together by ionic bonds.
In barium chloride, barium is a metal with an oxidation state of +2, whereas chlorine is a nonmetal with an oxidation state of -1, resulting in the formation of an ionic salt. lonic bonds exist between barium cations and chloride anions in barium chloride molecules.
Hence, the correct answer is A.
