Review: What kind of bond is most likely to form between the following? \( \begin{array}{ll}\text { 1. Sodium and chlorine: } & \text { 3. Carbon and oxygen: } \\ \text { 2. Carbon and hydrogen: } & \text { 4. Oxygen and oxygen: }\end{array} \)

Sodium and chlorine form an ionic bond, where sodium donates an electron to chlorine, resulting in oppositely charged ions that attract each other. This is akin to a dramatic love story where opposites attract, creating stable compounds like table salt. On the other hand, carbon and hydrogen typically form covalent bonds, sharing electrons to fill their outer shells. This sharing is like a harmonious duet, where both partners benefit from the relationship, crucial in organic compounds and the foundation of life as we know it!
