Key Concepts

Definition of Compounds

A compound is a substance formed when two or more different elements chemically bond together in fixed proportions. This definition highlights that compounds are distinct from mixtures, which can contain elements in varying ratios without chemical bonding.

Elements and Compounds

Elements are pure substances that cannot be broken down into simpler substances by chemical means. Compounds, on the other hand, are made up of two or more elements. Therefore, the statement that compounds always contain at least two different elements is true, as a compound cannot consist of a single element.

True/False Judgments in Chemistry

In chemistry, evaluating statements as true or false often requires a clear understanding of definitions and principles. When assessing a statement, one must consider the established scientific definitions and the relationships between concepts, such as the distinction between elements and compounds.
