Answer:
The best classification for an atom bonding with another atom is a chemical reaction.
Atomic bonding refers to the process where two or more atoms come together to form a molecule. This can occur through various types of chemical reactions, including covalent, ionic, and metathesis reactions.
In a covalent reaction, atoms share one or more pairs of electrons to form a covalent bond. In an ionic reaction, atoms gain or lose electrons to form ions, which then combine to form an ionic compound. Metathesis reactions involve the exchange of atoms or groups of atoms between two molecules.
All three of these types of reactions are classified as chemical reactions, as they involve changes to the chemical composition of the reactants to produce the products.
Therefore, the correct answer is:
