Step 1

So, we are looking for a figure with only one type of sphere (representing atoms). (b) A mixture of two elements consists of two different types of atoms that are not chemically bonded. So, we are looking for a figure with two types of spheres that are not Show more…

Key Concepts

Pure Compound

A pure compound is a substance formed when two or more different elements chemically combine in a fixed ratio. Its components are bonded together, resulting in a uniform substance with properties that are distinct from the elements that compose it.

Component Identification in Mixtures

Distinguishing components in mixtures involves understanding whether the ingredients are elements, compounds, or both. This helps in analyzing whether a mixture contains just elements, just compounds, or a combination of an element and a compound.

Mixture

A mixture is made up of two or more substances that are physically combined rather than chemically bonded. The individual components retain their own properties and can be separated by physical means.

Pure Element

A pure element is a substance that consists entirely of one type of atom. It cannot be broken down into simpler substances by chemical means and is represented by a single type of particle throughout.
