Detailed explanation-1: -All matter is made up of substances called elements, which have specific chemical and physical properties and cannot be broken down into other substances through ordinary chemical reactions. Gold, for instance, is an element, and so is carbon. There are 118 elements, but only 92 occur naturally.
Detailed explanation-2: -Fundamentally, chemistry is the study of matter and change. The way that chemists study matter and change and the types of systems that are studied varies dramatically. Traditionally, chemistry has been broken into five main subdisciplines: Organic, Analytical, Physical, Inorganic and Biochemistry.
Detailed explanation-3: -These particles are so small that we cannot see them with the naked eye. Hence, it can be concluded that matter is made up of particles i.e. matter is particulate in nature.
Detailed explanation-4: -Students are introduced to the idea that matter is made up of tiny particles called atoms and molecules.
