Final answer:
The compound with ionic bonds among the list is KCl (potassium chloride), which consists of a metal (potassium) and a nonmetal (chlorine), indicating an ionic bond.
Step-by-step explanation:
To identify the compound with ionic bonds from the list provided, it is useful to know that ionic compounds typically form from a metal and a nonmetal. Looking at the options:
- CO (carbon monoxide) consists of two nonmetals, so it features covalent bonding.
- H2O (water) also consists of two nonmetals, so it is a covalently bonded molecule.
- Ne (neon) is a noble gas, and as a single element, it does not form compounds under normal conditions.
- KCl (potassium chloride) is a compound formed from a metal (potassium) and a nonmetal (chlorine), making it an ionic compound.
- O2 (oxygen gas) consists of two of the same nonmetal element, forming a covalent bond.
Therefore, KCl is the compound with ionic bonds. It is comprised of potassium cations (K+) and chloride anions (Cl-).
