Which of the following is a characteristic of compounds?

Compounds are defined as substances that are formed when two or more different types of atoms chemically bond together. This means that compounds consist of molecules made up of two or more different elements, which can include elements like hydrogen and oxygen combining to form water, H₂O. The unique properties of a compound arise from the way the atoms are arranged and bonded together, distinguishing them from mixtures and elements.

The statement about compounds forming from various types of atoms captures the essence of what a compound is, emphasizing the need for at least two different elements to create it. This characteristic is fundamental in chemistry and helps differentiate compounds from pure elements, which consist of only one type of atom.
