In a compound, how are the atoms arranged compared to a mixture?

The correct answer highlights that, in a compound, the atoms are chemically bonded. This means that the atoms of different elements are joined together in a fixed ratio through chemical forces, resulting in the formation of a substance with distinct properties that are different from those of its individual components. This chemical bonding creates a new entity that has a consistent composition and structure.

In comparison, in a mixture, the substances retain their individual properties and can be separated by physical means. The atoms or molecules in a mixture are not chemically bonded and may coexist in varying proportions without forming a new chemical substance. This distinction is significant because it defines how compounds and mixtures behave and interact both chemically and physically.
