Dative Bond - English Definition & Meaning

Definition

"Dative bond" is simply another name for a coordinate bond. It emphasizes the *giving* or *donating* of the electron pair from one atom to the other. It is a type of covalent bond where one atom provides both of the shared electrons. Imagine one person paying for dinner for two people. 🍽️ One atom (the donor) provides both electrons for the bond, while the other atom (the acceptor) receives them. The bond formed is exactly the same as a covalent bond but the bookkeeping is different. Ammonia (NH₃) reacting with a proton (H⁺) to form ammonium (NH₄⁺) is a classic example.

Etymology

The term "dative" comes from the Latin word "datus," meaning "given." It directly reflects the concept of one atom donating the electron pair. The term is used synonymously with "coordinate bond" and shares the same historical development in coordination chemistry.

Related Words

Examples

• "A dative bond is formed when one atom donates both electrons."
• "The formation of ammonium involves a dative bond."
• "Dative bonds are important in metal complexes."
• "The stability of a metal complex depends on the strength of the dative bonds."

Encouragement

Dative bonds are another way to think about coordinate bonds. Use "dative bond" to show you understand how atoms share electrons unequally. You'll sound like a super-smart chemist. 💯
