Final answer:
FeCl3 is the most likely ionic compound among the choices since it is formed from a metal (iron) and a non-metal (chlorine), which typically creates ionic bonds.
Step-by-step explanation:
The compound most likely to be an ionic compound from the options given is FeCl3. Iron (Fe) is a metal and chlorine (Cl) is a non-metal, and compounds formed between metals and non-metals are typically ionic, where electrons are transferred from the metal to the non-metal.
The other compounds listed involve non-metals bonding together, which would more likely form covalent bonds where they share electrons.
To further assist you with understanding the nature of compounds, here are some examples of identifying whether a compound is ionic or covalent:
- BaO is ionic, consisting of Ba2+ and O2- ions.
- NF3 is covalent; both elements are non-metals.
- CaF2 is ionic, composed of Ca2+ and F- ions.
- Al2(SO4)3 is ionic, with Al3+ and SO42- ions forming the compound.
