📕Types Of Substances
👉The whole universe is made up of one or the other kind of matter. These matters are nothing but something that has mass and occupies space.
👉Although everything around us is a matter, this matter has a broad classification as the things around us are not all the same. The matter is classified into:
👌Pure substances 
👌Mixtures 
 Pure Substances
👉The term is a very common one related to our daily lives.
👉The matter that is made up of only one kind of particle or one kind of atom/molecule is defined as a pure substance. Also, the term itself explains the same where pure means only one kind.
👉The common exams of pure substances are gold, silver, iron, etc.
PURE SUBSTANCES
👉The pure substances are subdivided into two types on the basis of chemical compositions:
👌Elements
👉Elements is a subdivision of the pure substance which is made of a single kind of atom and can not be further broken down into a much simpler substance.
👉These elements are such that on applying either physical or chemical processes, none can break it into a more simple substance as in the case of a gold piece which if broken into pieces still remains the same gold piece.
👉The elements are further classify in to:
👌Metals: Metals are elements which easily lose electrons. For example: aluminium, iron etc. They are lustrous, good conductors, malleable, ductile and sonorous.
👌Non- Metals: Non metals are elements which easily gain electrons to become stable. For example, oxygen, chlorine. These non metals are non-lustrous, easily breakable, have low density etc.
👌Metalloids : the elements which possess the properties of both metals as well as non metals are called metalloids. For example, silicon, boron etc. they are basically called amphoteric in nature.
👌Noble gases: noble gases are those elements which do not react and have completely filled the outermost shell. For example: neon, argon etc.
👉Compounds
A compound is a type of pure substance which is formed chemically by the combination of two or more substances but in a fixed proportion.
Compounds are also further divided into:
 👌Organic : organic substances are those substances which are formed by combination of carbon-hydrogen bonds. 
👌Non-Organic: non organic compounds are the one which do not have the carbon-hydrogen bonding.
👉Mixtures are the type of matter which form by mixing more than one kind of atom, particle, or substance. Types of mixtures

👌Homogeneous: Homogeneous mixtures are the mixtures in which the different substances are mixed together but uniformly.

👌Heterogeneous: heterogeneous mixtures are those mixtures in which the different substances are mixed but the composition is not uniform throughout.
