Which type of chemical bond is present in potassium oxide (K2O)?

• A. Ionic bond
• B. Hydrogen bond
• C. Covalent bond
• D. Metallic bond

Answer: (A)

Verified step by step guidance

1. Identify the elements involved in the compound potassium oxide (K\_2O): potassium (K) and oxygen (O).
2. Determine the type of elements: potassium is a metal and oxygen is a nonmetal.
3. Recall that bonds between metals and nonmetals are typically ionic bonds, where electrons are transferred from the metal to the nonmetal.
4. Understand that in K\_2O, potassium atoms lose electrons to form K\^{+} ions, and oxygen gains electrons to form O\^{2-} ions, resulting in an ionic bond due to electrostatic attraction.
5. Conclude that the chemical bond in potassium oxide (K\_2O) is an ionic bond.
