Chemical bonding explanation

A chemical bond describes an attractive interaction that holds atoms or ions together in a chemical structure. Introductory categories include covalent, ionic, and metallic bonding. Real materials can show features that are not captured by a perfectly sharp three-category division.

Meaning and context

Covalent bonding involves shared electron density, ionic bonding emphasizes attraction between oppositely charged ions, and metallic bonding involves electrons associated with an extended metal structure. The categories help organize observations and models.

Examples and usage

Water is commonly described with covalent O–H bonds, while solid sodium chloride is modeled as an ionic lattice. Calling the lattice ionic does not mean it consists of separate NaCl molecules in the same sense as water molecules.

What to check

Bonding explanations should connect structure with evidence and properties rather than rely only on a label. Intermolecular attractions are also distinct from the bonds within a molecule. Specify which interaction the question asks you to explain.
