What is pure substance in matter?
A pure substance is matter that is uniform throughout and has consistent properties. All matter is made up of very small particles called atoms. Atoms are the building blocks of all matter. When a substance contains only one type of atom, it is called an element.

Complete answer: Substances which are made up of only one kind of atoms or molecules and have a definite composition throughout and have a fixed structure are known as pure substances.
What are two classes of pure substances?
Pure substances can be divided into two categories, elements and compounds. You already know that elements are pure substances that cannot be broken down into simpler substances. When elements combine, they form new substances called compounds.
What are the examples of pure substance and mixture?
Examples of pure substances include iron, aluminum, silver, and gold. Mixtures: Substances that have two or more different particles are mixtures. Examples of mixture include the salt solution which is a ‘mixture’ of two components, salt, and water.
What is the pure substance answer?
A pure substance is a substance which has only one type of atoms or molecules thereby having a constant composition and structure. Complete answer: Substances which are made up of only one kind of atoms or molecules and have a definite composition throughout and have a fixed structure are known as pure substances.
What is pure substance and mixture?
a pure substance consists only of one element or one compound. a mixture consists of two or more different substances, not chemically joined together.
What are 5 examples of substances?
Examples of pure substances include tin, sulfur, diamond, water, pure sugar (sucrose), table salt (sodium chloride) and baking soda (sodium bicarbonate). Crystals, in general, are pure substances. Tin, sulfur, and diamond are examples of pure substances that are chemical elements.
