Question

which of the following is an example of an ionic bond? answer: a f-f b o-f c na-o d na-na

Explanation:

Ionic bonds form between a metal and a non - metal. Sodium (Na) is a metal, and oxygen (O) is a non - metal. In option C (Na - O), sodium donates electrons to oxygen, forming an ionic bond. In option A (F - F), it is a non - metal - non - metal bond (covalent). In option B (O - F), both are non - metals (covalent). In option D (Na - Na), it is a metal - metal interaction (metallic bonding in bulk sodium, but not an ionic bond between two Na atoms).

Answer:

C. Na - O
