FAQS on calcium oxide cao is ionic or covalent

Q: Is calcium oxide (CaO) ionic or covalent?

A: Calcium oxide (CaO) is an ionic compound. It forms through the transfer of electrons from calcium (a metal) to oxygen (a nonmetal), creating oppositely charged ions (Ca²⁺ and O²⁻) held together by ionic bonds.

Q: What type of bonding occurs in calcium oxide (CaO)?

A: Calcium oxide exhibits ionic bonding. The large electronegativity difference between calcium and oxygen leads to electron transfer, resulting in a stable ionic lattice structure rather than covalent sharing.

Q: Why is calcium oxide (CaO) classified as ionic?

A: CaO is ionic because it consists of calcium cations (Ca²⁺) and oxide anions (O²⁻) arranged in a crystal lattice. This structure is typical of ionic compounds formed between metals and nonmetals.

Q: Does calcium oxide (CaO) have covalent characteristics?

A: No, CaO lacks covalent bonding. While oxygen can form covalent bonds, its interaction with calcium—a highly electropositive metal—results in a purely ionic compound with no electron sharing.

Q: How does the ionic nature of CaO affect its properties?

A: The ionic bonds in CaO give it high melting and boiling points, brittleness, and solubility in polar solvents—all hallmark traits of ionic compounds. Covalent compounds typically lack these features.
