Which statement is true about Chemical Compounds?

Chemical compounds are formed as a result of the bonding of different types of atoms. This process involves the combination of two or more elements with distinct properties to create a new substance with its own unique characteristics. When atoms bond, they can do so through various types of chemical bonds, such as ionic or covalent bonds, resulting in a compound that exhibits properties different from its constituent elements. This is a fundamental concept in chemistry, as it explains the diversity of substances in nature.

The other options do not accurately describe chemical compounds. For instance, while some compounds exist as liquids at room temperature, many are solids or gases, making the first statement incorrect. The second statement is also misleading, as chemical compounds can be formed from combinations of metals and non-metals, not just non-metals. Lastly, the concept of groups of similar atoms refers more to elements or molecules rather than compounds, which are specifically defined as combinations of different types of atoms.
