In this type of matter it consists of only one type of element or compound what is it?

The type of matter that consists of only one type of element or compound is called a pure substance. A pure substance can be either an element or a compound.

To identify whether a given sample of matter is a pure substance or not, you can follow these steps:

1. Observe the material: Look at the sample and note its physical properties, such as color, texture, and state (solid, liquid, or gas).
2. Conduct a physical test: Perform tests like melting, boiling, or other characteristic tests to determine if the sample undergoes any change or if it remains unchanged throughout.
3. Investigate its composition: If the material can be broken down into simpler substances through chemical reactions, it is not a pure substance. However, if it cannot be broken down chemically into other substances, it is likely a pure substance.

By following these steps, you can determine whether a sample of matter is a pure substance, made up of only one type of element or compound.
